Kids say the darnedest things at gigs:
KID (walking by the band): Are you going to play jazz?
BASSIST: Yes we are.
KID: Is that a bass (pronouncing it like the fish)?
...BASSIST: Yes, it's a bass (pronounces it correctly).
ME (after kid is out of earshot): Yes, it's a bass [like the fish]. You play a lot of scales on it.
