Almost 30 years ago I went to a Penn and Teller magic show. They did their bullet catch (classed up but basically the same trick people have been doing for a century) and other stuff I don't really remember.

The trick I vividly remember was just Penn standing behind a table, putting a piece of green cloth (like a surgical thing) over a water balloon, and then giving a long speech of all the damage that friends of his had survived, as he stabbed the balloon (under the cloth) repeatedly in time with his speech, and talked about the wonder of medical science, and how doctors he knew had saved people from all these horrendous accidents and damaging the balloon in sync with every example.

And then he removed his hands from the table, holding them up to the audience, leaving the balloon still under the surgical barrier, and said "And the other thing that doctors will tell you, if get a couple of beers into them, is that sometimes people just die for no reason at all." And the balloon collapsed right on cue.

I can't seem to find a video of it but I remember it clearly.
