Muffler bearings 

A real howl for prank-calling kids of our 70's past: get a naive auto parts clerk on the phone (dumb teen, etc.) and ask for "muffler bearings". A bigger howl when they realize the gag, and get back on the phone and cuss you out.

Related to asking for "Johnson Rods"

see above described usage
