What a gas!

I just read the Father's Day Freakonomics blog post by Steve Levitt discussing his father's greatest contribution to science. It is the funniest article I've read on a such serious scientific matter...! I guarantee it'll totally crack you up. More importantly, it will appeal to your inner boy! And even if you are not of the male persuasion, I guarantee you'll enjoy it---even though you may never admit to enjoying it!
