Darn. I was going to guess Sonny Dykes. I read on BI that his clown show was a real hoot. Also, didn't he win "Best Straight Face in a Comedy Role" for his 2013 performance on The Drive?
(Timed to that year's Winter Olympics, in which he didn't medal -- he won Gold in Nagano in 1998.)
I still remember a ridiculous-but-still-kind-of-funny skit in that episode where Jonny Moseley is this superhero who "flies around the world on a never-ending dinner roll" (the 'dinner roll' was his signature trick) and he would solve problems. He made peace in the Middle East by dropping a pizza from the sky, over which the combatants found common ground because everyone loves pizza. (Couldn't write that with a straight face.)
