(As Santa's Little Helper runs off to join the Springfielders jogging with George Bush Snr)

Homer's brain: There it is, Homer - the cleverest thing you'll ever say and no one was around to hear it.
Homer: Doh!
Or as the kids are revealing the adults' secrets on radio:
Lisa: And who is it who's been practising medicine without a licence?
(Dr Hibbert looks uncomfortable and sweating)
Lisa: That's right - Homer Simpson!
Voice in the background: Doh!

Film Festival episode when Todd is sailing away Flanders says "Flanders to god Flanders to god come down from heaven and save our Todd" then the tree falls and stops him.

"Around the house
I never lift a finger
As a husband and father I'm sub par
Because I'd rather have a beer
Than win father of the year
I'm happy with things the way they are"
(Homer singing in the Mary Poppins tribute episode)
