We need more cowbell...

...true story: A friend of my wife plays bluegrass banjo; she's pretty good. The band leader got him a new girlfriend whom he imposed on the rest as "our newest band member!" She was completely without talent -well, musical talent I guess- so he put her on the washboard.

Yep. He actually said it...

"We need more washboard!"

The band broke up. By way of explanation, Debbie sent him the youtube clip of the cowbell sketch.
