I’m a real sucker for a good pun, and I have quite a few saved up, some original some not, waiting for that one time where the opportunity arises to just zing one in there. I mean, how often do you get to say “The trumpets were lost at C!” (rehearsal letter ‘C’)?. Anyway, here goes:
Two Eskimos sitting in a kayak were chilly, but when they lit a fire in the craft; it sank, proving once again that you can’t have your kayak and heat it too.
You forgot the classic rehearsal letter pun, “Go to L!” or, “violas, go to L!”
Of course that would be used with respect to the violas :). Nice one.
