Yep. The Pooter. A simple fart generator made by Jack Vale.
What's so great about it, you say? Well, watch these videos and check out some of the other episodes if you can:

It's not like one 'o' those cheap fart machines. The ones the Pooter makes are realistic. You squeeze it and depending on how you squeeze it, you might get a different fart.
