what was the episode where

Mr Garrison invents a new mode of transport, its like a globe, but the controls to make it work go up your ass and in your mouth?

"The Entity". Season 5 episode 11.

Don't forget about the "jack off " handles. This is a very complex machine, as it has three sets of controls.

But don't the buttons on each side perform the same function? Why can't you just use those instead of the jack-off handles and blow-job control stick?
