On Saturday, he accidentally added a profanity.
On set for the SMU-Houston game, Corso got tangled up with his SMU prop, a cheerleader's megaphone, prompting a two-word vulgar outburst as he tried to make his pick for the game. Corso then put on the Houston mascot head -- muffled a few seconds too late.
Corso later came back on air during ESPN's broadcast of the Nebraska-Michigan game to apologize.
"Earlier today on `College Gameday while picking the SMU-Houston game I got a bit excited and used an expletive that I shouldn't have used," Corso said. "I apologize and can promise it won't happen again."
