Ahem, I believe Sam Kinison was the teacher in Ferris Bueller's Day Off:
Professor Terguson: Is she right? 'Cause I know that's the *popular* version of what went on there. And a lot of people like to believe that......I wish I could, but I was *there*. I wasn't here in a class room, hoping I was right, thinking about it.
I was up to my knees in rice paddies, with guns that didn't work! Going in there, looking for Charlie, slugging it out with him; While p*&&%s like you were back here partying, putting headbands on, doing drugs, and listening to the g**&amn Beatle albums!
Oh! Oh! Oh!
