I know, I know...you need that perfect gift for your friend-relative-enemy. But you've ALREADY given them The Big Book of Gross Stuff! What now?
Here's one possibility: An official art book! Just be careful...because you might slip up and get an Official Fart Book by accident!
The Official Fart Book so official? Good question!
I would THINK that the author consulted with a panel of experts when doing his research. But since my friends and I weren't interviewed, I have to wonder!
