"Why did the chicken cross the road?"
"Someone was playing an accordion on the side he was on."
"What's the difference between a dead chicken in the road and a dead accordion player in the road?"
"The chicken might have been coming home from a gig."
"What's the difference between accordion music and the sound of a chicken being attacked by a weasel?"
"The chicken might be in tune."
(Actually, I grew up in a rural area of Eastern Iowa, and I kinda like accordion music)
My favorite accordion joke;
An accordion player was going to have lunch and left his accordion in the car.
Halfway through lunch, he realize that he left the car unlocked.
He ran out to the car, but he was too late;
there were two more accordions in his car.
