For those who missed this the other day, here's Jon Stewart making the most of his newly retired status by showing up to challenge John Cena on WWE. I don't know why he insists on growing that awful goatee when he's not on the air- I'm telling you, all I can think is Col. Sanders whenever I see it. But aside from that, I am so not the target audience for this wrestling stuff. Arrow's Stephen Amell, a devoted fan, also showed up for his big fight in this episode, but to me this is such a guy thing, I can't even tell you.
