OK, so we can't say for sure that this was actually a fart, nor can we say for sure who was responsible for it. But we choose to believe that it was a fart, and that it came from Skip Bayless.
Reasons for believing it was Skip Bayless: He's got a total oh-shit-I-need-to-fart look on his face, and a Bayless fart makes this video much funnier than, say, a cameraman fart does.
Reasons against believing it was Skip Bayless: He kind of always looks like that.
Hope you enjoyed the fart.
