Stabbed in the butt

Bradley, Janet and Laura are contestants on Stabbed in the Butt in "Bigfat". On the show, contestants who answer a question wrong get stabbed in the butt, hence the title.

The host asks Bradley if he knows what the atomic weight of nitrogen is. Bradley, not knowing the answer, panics and attempts to flee. The host sends three men after Bradley to stab him in the butt.
