Smells Like Hell.

The Lineup: Tom Hanks and a sea of men of the cloth, one of whom is grabbing his crotch (surprise, surprise).
Fart Factor: A weak 4 out of 10. Everyone knows priests fart in their frocks all the time, so locating the source would be as easy as grabbing any of them by the shoulder.
Most Likely Fart Factor: The priest who just passed by the foreground– you see how he opened up his robes? Jeez, somebody light some incense in here.

Quick, inhale the asbestos!

The Lineup:

3 construction workers. When you're working your fingernails to the grindstone, you're bound to let a few slip. After all, it's not like you can get any dirtier. These guys may have the most farts per capita of any of our previous posts. Except that bearded fat guy.

Fart Factor:

5 out of 10.

Most Likely Fart Suspect:

The man on the right. What is that hole in the crotch of his pants? Is it part of a burning flame?
