Not that Jasper has a ton of widely known quotes but his stint as a substitute teacher explaining what does and doesn't result in a paddlin' is easily his best known
My friend and I have been using "that's a paddlin'" to express disdain for regrettable actions for 20 years and will likely continue to do so until one of us is dead.
You should accept both Charles Montgomery Burns and Monty Burns, which I tried each of. Probably Charles Burns as well, even though he has never been called that ever. Also, it was Lisa who gave Ralph the Valentine's card with 'I choo-choo-choose you!' on it, so really that should be a Lisa quote, although Ralph says it too.
"What kind of catchphrase is that?"
