This May Just Be ESPN's Funniest 'SportsCenter' Ad Ever [VIDEO]

ESPN's long-running line of "This Is Sportscenter" ads take a whimsical and bizarre angle on the legendary show's behind-the-scenes productions, imagining scenarios and backstories that, for all we know, could actually be true. They've produced some really funny spots over the years.

But the latest offering -- which purports to reveal that straight-laced NFL analyst John Clayton actually rocks a gnarly ponytail, head-bangs to Slayer and still lives with his mother -- may be SportsCenter's best ad yet. That was the chatter on the social web after the spot instantly started spreading in sports circles upon hitting YouTube Thursday morning -- high praise considering the campaign's hilarious history.
