I love this movie as well, it really never gets old. I can sit and enjoy it any time I need a good movie to watch. We quote it often as well.
My husband refers to hair gel as Fop. And he never knows where it is, so I hear “Where’s my goddamn Fop!” All the time.
Also good in many situations are:
Ulysses Everett McGill: Damnit, I am the paterfamilias!
and:
**Delmar: **It was a whole… gopher… village…
And when the room goes silent:
“Baptism!”
