On his 2/5 B.S. Report podcast, ESPN/Grantland's Bill Simmons discussed pulling a prank on Dick Costello during the Super Bowl. The two were in box together at the game when Simmons pulled out his phone, turned to Costello, and said, "Oh, so Twitter's down?" He said Costello freaked out and almost had a heart attack. Then got really upset when he found out it was a joke. The story starts at the 37:30 mark of the podcast. Tried to add a link, but it won't let me. Thought you'd enjoy listening.
