Cecil Taylor, Keith Jarrett, and Pee-wee Herman walk into a bar.

The bartender says, “What’ll it be?”Cecil Taylor launches into a 45-minute solo order that nobody understands, Keith Jarrett complains the glassware is out of tune, and Pee-wee Herman just laughs his laugh and says, “I know you are but what am I?”

The bartender shrugs, “Great… tonight free jazz and Dada.”
