The funniest part of this whole strip: 9 out of the 10 websites I found about colon cleansing urged you not to do it. It does more bad than good.
This was a joke that I had come up with when I first designed these guys. Stabber likes to take things a tad too literally, so he's cleaning his colon with his own hands instead of eating fiber of whatever. He's a real man.
I've also noticed that their hair is a lot crazier than when I drew it on the first strip. Oh me and my lack of consistency.
