Dental plan. Lisa needs braces.

White Carl

Arguably the best written episode in the show's history.

You're right Marge, first thing tomorrow I'm going to punch Lenny in the back of his head.

Mr. Burns came very close to getting those fools to give their dental plan for beer.

Dental plan

And Gummy Joe! Where would YOU be without our dental plan? This episode also has at least three of my favorite Simpsons gags of all time. The screen door at the end of the elaborate security system, Mr. Burns as the Grinch, Homer's Curly impression...

why do you think they use a different take of "dental plan" for when he's remembering it vs when he actually says it

A true classic

Possibly the best Homer joke ever

Last Exit to Springfield is the best tv episode of all time
