hmmm... A buddy of mine had a thing on his Mac that when you emptied the trash can Oscar the Grouch stuck his head out the trash can and sang to you.

One Saturday morning he woke up to discover his 5 year old son had taken every icon on his computer, one by one, and thrown them in the trash then emptied it.

I don't know it if was more fun but it the kid enjoyed it.

Given that christmas tree ornaments only come around once a year, I have to say that dropping your juice cup off the high chair table and watching mommy and daddy pick it up over and over has much more quantity of fun, although quality of smashing ornaments is hard to beat.

How about urinating in the produce aisle of the grocery store?

(P.S. This is unusual given that I do not live in San Francisco.)
