Looking at the essintials for puns, gags, jokes and whatnot, I needed some help. The basic idea was from listening to Chapelle's Show and drawing. It was the Charlie Murphy story telling about his encounter with Rick James. That one line, "Cocaine's a hellavu' drug" always made me laugh.
One thing led to another where I included Derpy.
It went from Cocaine's a hellavu' a drug.
Then Derpy's a hellavu' drug.
I got confused and stumped. Fortunately I got some helpfull humor from  dcrabbit. Great idea dude. Credit goes to you. :3 Thus here's the joke folks. ^_^
