Why so serious?

What gets your blood boiling? Makes your skin itch? When are the times you cannot simply shut your mouth but must be heard and understood? Everyone stands for something slightly different in their hearts. I'm curious George over here and wondering why are you SO serious!

I know it's way lame but come on my mom read those books to me as a kid and I loved em! Even the pop-up ones!
...they gotta be around here somewhere...
