I was browsing hahaprank for something new to do at work - it's gets boring
there at times and ran into this. I am already planning where to hide it-
should be a "blast".

The Remote Controlled Fart Machine emits 15 different realistically
embarrassing gas passing sounds, and has a remote control that allows it to
be operated from as far as 100 feet away! Simply hide the Fart Machine in an
inconspicuous spot, and let her rip!
