Thought of this when walking home from the tire shop where I left my car to get my breaks checked.

Okay for those of you who don't get it: Y-know how when punks steal your tires they leave your car sitting there on cinder blocks?....................*pa-dum-pish*

Everyone I showed this to in my family didn't get it so let's see how you guys do. Be honest now, is it easy to understand?
