“I saw trombone players at the park today. Couldn’t swing and kept complaining about the slide”

A trombone riddle was posted on Twitter on April 7, 2012:
 
Q: Why is it no fun to go the park with a trombone player?
A: They can’t swing and complain about the slide.

 
Forms of the “swing” and “slide” trombone joke have been cited in print since at least 1999.

How do you spot a dobro player’s kid at the park? He’s the one that won’t shut up, is all over the place, doesn’t know how to use the slide and can’t swing!

Went 2 the park w/a trombone player. No fun. He just bitched about the slide and couldn’t swing.
