Houseboat Hooligans: Chumming for Clowns!

There we were, enjoying another sunny day on the water floating around on the houseboat. Somebody produced a bag of balloons from somewhere, which we proceeded to blow up. I think they might have been water balloons or something. So there are a few balloons floating around the inside cabin. We start off to our next destination, and then Joe starts throwing balloons out the window.

"Joe, what the heck are you doing?!" we ask.

"I'm chumming for clowns!" came his reply.
