It's as good a theory as any. I'd love to see an episode where they explain it; maybe Frankie goes to the DMV to renew her license and brings Bloo along because he won't stop screaming and whining when she tries to leave him at the House. He soon discovers that the DMV is even more boring than Madam Foster's fabric store. The rest of the episode has Frankie trying to keep Bloo under control and out of trouble as he desperately tries to entertain himself. At the end of the day she looks like hell, and off goes the DMV camera. She gets justice, however, as the DMV camera also catches Bloo doing something horrifically embarassing (I'll leave that part to your imaginations), and she makes him sweep and mop every floor in the house to keep the photo private.
