There is a tv program on ESPN that is called Around the Horn (ATH). There is a rotating panel of journalists that comment on the current sporting events. The show is hosted by Tony Reali. Anyway, there is a part of the show called "Buy or Sell." In this segment panelists choose to buy or sell a certain event and explain why. (Kate Fagan is my favorite on the show).
So when someone said it'd have to be Saturday Evening Live (SEL), I said I'd SEL(l) that idea. On the show, ATH, that would mean that I didn't like the idea.
It was a very corny joke. Made worse
