Australian diver Matthew Mitcham is hoping to repeat his gold-medal performance from the 2008 Olympics, but he has to wait to dive until Aug. 10. Between now and next Friday, Mitcham has some time to kill. He can only do so much training and tweeting, so he put his musical talents to use with a lovely version of the well-known Beyonce song, "Single Ladies," on the ukulele.

No matter how this one ends, Tunisia will never forget how it started. (Getty Images)Well, this wasn't what we expected to see at the start of Tuesday's preliminary-round matchup between Argentina and Tunisia in the men's basketball tournament at the 2012 Summer Olympics in London. After 10 minutes of play, Tunisia — the only team in the field without an NBA player on its roster, FIBA's 32nd-ranked team in the world and 47-point losers to the United States on Tuesday — just doubled up the heavily favored Argentines in the first quarter, leading 28-14 after the opening 10 minutes of play.

As it did against the United States, Tunisia came out of the gates strong, showing no fear of its more highly touted opposition and attacking from the opening tip. Behind a strong opening quarter from center Salah Mejri — eight points, five blocks, three rebounds and a pair of strong drives for thunderous dunks around plodding Argentina forward Luis Scola — Tunisia shot 11 for 18 from the floor, a sterling 61.1 percent, in the opening frame and made 4 of 7 shots from 3-point range. Argentina, on the other hand, opened ice cold, missing 13 of 18 field-goal attempts (27.8 percent) and five of six long balls. Tunisia gave Argentina fits on the defensive end in the opening 10 minutes, forcing turnovers, blocking shots and using their size advantage on the interior to protect the rim against Argentine penetration.

The U.S. women's eight rowing team won its second straight gold medal on Thursday.  Coxswain Mary Whipple led the women to the win by yelling, cajoling, sometimes even cussing at them to get them across the finish line first. Now that they have the gold, how does this group of intelligent, accomplished women retaliate? By keeping up with tradition and throwing her in the water, of course.

Whipple is 5-foot-3 and weighs around 100 pounds. She didn't stand much of a chance against the eight rowers, whose height starts at 5-foot-9.

As his mother, Ike, explained to "Today" this week, Ryan doesn't have time to get involved in relationships. He's more of a love 'em and leave 'em type.

"He goes out on one-night stands," Ike said during an interview. "He's not able to give fully to a relationship because he's always on the go."

You hear that ladies? Ryan rounds the bases on opening day. He wins gold in the heats. If forgetting your name was an Olympic sport, he'd have more medals than Michael Phelps. Or something like that.

Either Lochte and his mom are super-close and she knows way too much about his love life, or Mrs. Lochte has fallen victim to the oft-hilarious "mom slang," where she means something else than the current usage. In this case, rather than speaking

The U.S. women's eight rowing team won gold on Thursday, continuing a dominating run that includes two golds and a silver over the last eight years. Led by coxswain Mary Whipple, a tiny dynamo who keeps her team focused, the team hasn't lost a race in eight years. They beat Canada, the silver medalists, by more than a second.

An undefeated run lasting since Beijing is impressive on its own. But it grows more impressive when you take a look at each rower's academic credentials.

Caryn Davies has a bachelor's from Harvard and is pursuing a law degree from Columbia. Caroline Lind graduated from Princeton then earned a master's degree in accounting from Rider. Esther Lofgren has a degree in economics from Harvard. Susan Francia has a bachelor's and a master's degree from Penn. Stanford, Cal-Berkeley and Yale are also represented on this team. Several of the rowers have postgraduate degrees.

You'll have to forgive us for missing this during the U.S. men's national basketball team's Olympics-opening win over France on Sunday — unlike American sprinter Tyson Gay here, we were actually awake and watching the game.

Thankfully, Gay's teammate Tony McQuay was kind enough to capture the moment for posterity and share it with the world, which even Gay, the American record-holder in the 100 meters, had to admit was a pretty decent goof:

"He got me pretty good," Gay said.

Did he get revenge?

"I haven't yet," he said.

His plans might have to wait. He's got bigger things on his mind.

Namely, preparing for the start of 100-meter heats on Saturday. Gay, who holds the second-fastest time ever in the 100 meters, will be looking to outpace Jamaican favorites Usain Bolt, who set the world record en route to winning gold in Beijing in 2008, and Yohan Blake, the current 100-meter champion. Well, at least we know he's been getting his rest.

LONDON — So you want to be a 77kg (170 pounds) weightlifter, eh? FYI: Sometimes things work out as they did for Sa Jae-hyouk of South Korea during the London Olympics on Wednesday:

That thing that looks like a bran muffin under Sa's skin on his right arm would be his elbow, which was dislocated as he attempted a 162kg (357 pounds) lift in the snatch, according to the Daily Mail. He screamed in pain, as medical and team personnel rushed over to assist him at ExCeL arena. It was all quite unsettling.

British cyclist Bradley Wiggins won his fourth gold medal on Wednesday and gave the host country its first gold medal of the Olympics. It was a good day for Wiggins, and he is now finished competing. What does he do to celebrate?

Well what a day, blind drunk at the minute and overwhelmed with all the messages, Thank You everyone it's been emotional X

— Bradley Wiggins (@bradwiggins) August 2, 2012

That's right -- he gets blind drunk. According to the Associated Press, his drink of choice is a vodka tonic, and something tells me he's not having to pull out his wallet very often. He absolutely should celebrate his win. Before the Olympics, he won Tour de France, the most grueling of road races. Five days later, he had a starring role in the Opening Ceremony, then won a gold. He earned that vodka tonic.
