I remember the corn line from the Austin Power's movie with Fat Bastard, but we haven't watched all of PL yet. Really doesn't sound like a PL line though - too potty. FWIW, there was a one-season "Ferris Bueller" show that wasn't nearly as good, so it might have been that one instead.
If quirky comedy is what you're after, here's some others.
Sledge Hammer and Police Squad
The Tick - live action. The cartoon was OK too.
My Name Is Earl for something more recent and karmic.
