I guess this is an old one but I heard it for the first time tonight.....thought it was funny enough to share. Bass player and drummer are fighting in the parking lot of the bar they're playing at. The bouncer goes out and breaks them up and says "What the heck is going on here?!" The bass player says "I'm the bass player and he's the drummer in the band playing here tonight." The bouncer says "Okay fine....so what the he11 are you guys fighting about?!" The bass player says "Well the drummer just told me he de-tuned one of my bass strings..." The bouncer says "Okay fine... so why are you fighting?" The bass player says "He won't tell me which one it was!"
