WATCH: Porta-potties sing "Go Cubs Go"

CHICAGO (FOX 32 News) - That moment when you're about to take a tinkle and your toilet starts singing "Go Cubs Go."

Every family has a holiday tradition and the Service Sanitation family is no different.

This one just happens to be singing porta-potties.

The portable restroom company gave the porta-potties faces and made them sing Christmas carols as well.

The Jingle Johns can be seen this Friday in Merrillville at the Southlake Mall from noon to 5 p.m. if you're interested.
