One of the contestants on Last Comic Standing this season is DeAnne Smith, who spent the beginning portion of her set in the most recent episode joking about a gig at an atheist convention:

This isn’t even the weirdest gig I’ve ever done. I performed comedy at an atheist convention recently. An atheist convention! And it was amazing because I had been praying for an opportunity like that.
Easy joke, but well played… 🙂
Smith was one of 28 contestants to advance to the semifinals.
