What would you do with a trebuchet?

This rich British guy flings huge stuff with his trebuchet, a replica of a medieval artillery piece. Most wealthy people just party and humiliate themselves in their spare time, this guy destroys cars and pianos. I'm just waiting for him to go Monty Python-style and throw a cow.

He says he wants to get a bigger one, maybe fling a double-decker bus. I just think it's cool that we share the same dream.
