Dexter's Laboratory S02 E16 Shoo, Shoe Gnomes

"He skips grades. She just skips"

Dexter calls upon the "shoe gnomes" to repair his boots, but can't rid himself of them afterwards. The only way to get rid of them, according to Dee Dee, is to kick them in the butt. Dexter gets rid of the last one with his boot, but it's damaged again.
