Lots of good stuff already. I'd add:
Eating contests - let's go watch some slob shove hot dogs down his throat!!
Over The Top Birthday Parties - like every 10yr. old (or anyone else) really needs a family get together AND a cupcake party at school AND a huge neighborhood bash for 150 of his/her closest friends with caterers, live entertainment, a yard full of bounce toys and of course a professional fireworks display.
