Boo, I'm sure you've heard this one already but . . .

How many tenor sax players does it take to change a flat tire?

Four - one to change the tire, one to work the jack, and the other two to contemplate on how John Coltrane would have done it.
- Scott

I too love John Coltrane's music but thought you all would get a kick out of this classic sax player's joke anyway.
