Steven Gerrard and Robbie Keane prank Giovani dos Santos

Sometimes, Steven Gerrard and Robbie Keane like to have a little fun with their teammates. Their quest for a joke caught Giovani dos Santos by surprise over the weekend.

LA Galaxy duo Gerrard and Keane sketched out a plot to prank dos Santos as he signed autographs. They even donned elaborate and ridiculous costumes to hide their identities before springing the so-called surprise on their unassuming teammate.

Watch the whole prank -- from plan to execution -- unfold, courtesy of the Galaxy:

"I wasn't scared or surprised, but I didn't expect it," dos Santos told LAGalaxy.com after the prank. "I was like, 'What's going on?' But I turned around and I heard the voice of Robbie Keane. I knew straight away that they were making a joke with me."

Well done, lads.
