Could you ask a lady to remove a stocking to make a 'get you home' fix a la old school fanbelt?I'm late to the party, but I came up with one not mentioned:
The bass drum pedal spring that breaks. No amount of foot technique will save you at that point. The overall effect is as if your bass drum grew a couple wheels and suddenly took off away from you, leaving you with nothing but the flat floor underneath.
Or ask a lady to remove a stocking to make the crowd forget about the lack of drumming?
