Mario Lopez Underwear YouTube Video: 'Extra' Host Honors Super Bowl Bet at The Grove

Ladies, aren't you glad the 49ers lost? So was Maria Menounous, Extra's host, when she had co-host Mario Lopez honoring their Super Bowl 2013 bet. Menounous, who was rooting for the Ravens, dared Lopez — a San Francisco 49ers fan — to strip down to his (purple) underwear and run around The Grove wearing a Raves helmet if Baltimore became the champion (Menounous lost the bet last year). Watch the video below where Mario "man of his word" Lopez does just that. Is this a preview to ABC's upcoming Splash USA? If anything, it's some motivation for guys to take the gym seriously this year (as ladies will no longer settle for our beer guts).
