Let me just say, tonight's band rehearsal was the funniest yet.
This crazy guy, Bill, he's... crazy-like. He has like 75 trumpets (110 cornets?) because he likes to buy trumpets. So, he shows up late to rehearsal, and then, he's all "Oh, I forgot my music!"
He had just left it in the car, though, so he ran out to get it while we started the first tune. Then, he gets back in and sits down, and he says "There's a quarter in my trumpet!" and he showed me, and it did indeed look like a coin was stuck down in the bell of his trumpet!
So, he borrows my dad's spare trumpet, and then he realizes he didn't bring any valve oil (this stuff you use to lube the trumpet finger thingys - also known as valves). So he borrows that from my dad.
Then, my dad finds this long metal stick thingy, so he hands that to Bill so that Bill can retreive the quarter from his trumpet.
Bill sticks the thing in, and out pops a dime!
Naturally, we all made the joke "Wait - another dime and a nickel will come out in a minute!"
Then later he did something goofy, but it's so trumpet-specific that I would have a difficult time describing it to non-brass players.
For some reason, having a coin stuck in one's trumpet is really really funny to me.
