Farty Talkies

The Farty Talkies are most likely some version of the Stone of Farspeech. We were most likely high and/or drunk and reeling from the possible shenanigans that could be achieved with the Ring of Grammarian and decided to change "Farspeech" to "Fartspeech", and the rest is history. 
For the most part, these seem to work like normal walkie talkies, except everything gets translated somehow to farts, and for some reason we can all understand the fart language so even though it all sounds like farts, it's actually an effective means for us to communicate with each other. 
Doug P. Thug, the head of our thug army, has a Farty Talky in case we need to reach him. I believe Grand Master P, the dragon emcee whose hip hop career we manage, has one as well.
