Penn & Teller have a television show on Showtime network where they call BullShi** on basically everything. They show is for mature audiences. Plenty of colorful language and nudity, so don't watch it with kids around.
On Thursday, July 9 at 10pm, Penn & Teller call BullS*** on the "theory that politicians and other alarmists exclaim that playing video games leads to teen violence by handing over a real semiautomatic weapon to a nine-year-old video game player to see if he becomes a human killing machine." Should be a good show.
