I'm going to assme this is a Transformer doing one of those tricks where you place a cinderblock on your chest while lying on the floor and a buddy then smashes the block with a sledge hammer, but he misses the block and it smashes your nuts. Everybody laughs and you end up being a Youtube star.

Yup, [retty sure I'm right about what's going on in the cover.
