The Getty Images caption for this picture reads: "Zlatan Ibrahimovic of PSG gives funny instructions to all the security guards after borrowing a walkie-talkie from a bodyguard, on his way to the Paris Saint Germain training session held at the Aspire Academy for Sports Excellence on December 30, 2012 in Doha, Qatar." This raises a number of questions, which I will now answer for you.
First, the bodyguard mentioned there isn't for Zlatan, it's for his teammates. As we know, he has a habit of kicking his colleagues and he wasted no time in doing so upon joining PSG last summer.
Second, Zlatan only "borrowed" the walkie-talkie from said bodyguard after kicking him into outer space.
Third, the instructions he gave all the security guards weren't meant to be funny. He seriously wanted them to hunt down Pep Guardiola and put things in his soup and then go home and conceive children and then name each and every one of those children Zlatan.
And fourth, Zlatan found this prank quite satisfying indeed...
