Happy Clown is a local business with several diverse branches.
In "Hot Rods from Heck!" Freakazoid uses the Freakmobile to skywrite an ad for the Happy Clown Cafe on Route 10.
In "Virtual Freak," Lobe (breaking character between takes) says the only role he is currently up for is a local spot for Happy Clown Breakfast Soup.
In "Two Against Freak," Cave Guy bounds over the Happy Clown Medical Building.
