Monty Burns, in the parody of Be Our Guest, See My Vest, from the 101 Dalmatians-esque episode:
"Like my loafers? Former gophers!
It was that or skin my chauffers..."

Oooh! That one kills me - and I'm a big fan of Flanders, particularly when the community rebuilds his house so poorly that he's reduced to profanity, Flanders-style:
"Hell-diddly-ding-dong-crap!"
The Flanders family reunion had me in paroxisms of laughter over Pablo Flanders':
"Buenos ding-dong-diddly dias, senor!".

Mostly, when I watch TV I walk away feeling it was a grand waste of time. Not The Simpsons... whose creator, by the way, is originally from my hometown of Portland, Oregon,Hi Geoff! where the streets include Flanders, Lovejoy, Terwilliger (Sideshow Bob's last name), and Bort.
