"I'm a bit ashamed to say I was one of the little SOB's who did this once. Seemed like a fun thing to do at the time, but I felt pretty guilty after the fact (not enough to confess, however)."

I never flushed one down the toilet. What I did do is put one under a garbage can that was empty and turned over. No damage but it was fun.

You do need water (to conduct the force of the explosion). An M80 in a dry pail will dent the pail. An M80 in a pail of water will split the pail wide open and spray water all around.
