The small robot man who controls the function of your anus. Exitron works tirelessly day-in and day-out to make sure no fecal matter falls from your butt hole without a proper notification before hand.

As you reach the age range of 65+, Exitron begins to deteriorate and waste can periodically leak from your anus without prior warning.
Colleen: I've been shitting myself a lot lately, should I be worried?
Scott: Eh, it's probably just your exitron, he may have started to deteriorate recently.
Colleen: Thank Moses! I was worried I had infected taste bud syndrome!
