But he clearly wasn't joking around when he fired off this tweet on Saturday evening: "Check this out, we have a ghost in our house this week & I'm not joking we have had some very strange goings on every night," Poulter said via his Twitter account.
After the initial tweet, he started to list all of the things that were going on in his rental house, as well as ways to catch the ghosts on tape.
-- "We have a dead bolted door in the house & every morning that door is unlocked & slightly open. It's happened 7 times already."
-- "No joke for real, very bizarre the door is pretty solid with a dead bolt & number of times it's been unlocked & open. Calling home owner now"
-- " @Graeme_McDowell I might join you mate we have a ghost in our house and it's given a strange feel in this house."
-- "I should ask @golfchannel or CBS if I can borrow a camera & set it up on that door for the night. My camera won't video for that long."
No word yet if it followed Poulter to the course on Saturday and caused him to shoot his worst round of the week, a 4-over 75, to fall out of contention at the Heritage Classic. You never know, maybe the ghost was just looking for some golf tips, or a suggestion on a hair gel that holds for up to 24 hours. Both seem like logical questions a ghost would ask him, right?
