Chad: "Okay, okay. A Care Bear and a ninja got in a fight. Who one?"
Me: "The ninja."
Chad: "No. The Care Bear. You see, it had just eaten an eighteen inch burrito, and it farted. The stank smell killed the ninja! HA HA HA HA HA HA HAAA!!!" *more annoying laughter continues*

So Funny I Forgot To Laugh
It's a webcomic. One day, a neurotic artist decided to create a stick figure comic. Then God said, LET THERE BE CHARACTERS, and appeared Suds, a cynical drinking sarcastic smartass; Perry, a shy guy lost in his thoughts; and Avital, the dumb creator herself. Together, they will overcome horrifying obstacles. Like CVS.
