As a side note, does anyone else ever listen to the show and wonder what jokes are from Tom and what are from Jon on the calls? I always assume any jokes about sexual deviancy are from Jon. Is that fair? 
Three factors IMO:
1. Tom acts a prude on air
2. Jon has spent much of his adult life in the debauched world of indie rock touring
3. That old saying "a scharpling on the streets, a wurster in the sheets"
