one of the funniest south park characters, mostly because he's exactly like all Health education teachers ever. he goes in circles about how drugs and drinking is bad, along with sex education, without explaining anything, because he has no idea. It's hilarious to watch, especially if you're in a health class currently, and can make the comparison
Mr. mackey on drugs:
"drugs are bad, m'kay, so, if you do drugs, you're bad, m'kay, because drugs are bad. they can hurt your body, m'kay, cause drugs are bad, m'kay...

Mr. mackey, on sex education:
"So then the man puts his penis... he puts his penis..."
*kyle* "haven't you ever had sex before?"
"of course i have, it's just been a while. lets see, i'm pretty sure he puts his penis... dang it, where did i put that thing???"
