re: Favorite Gene Wilder movie or scene

Dr. Frederick Frankenstein: [to Igor] Now that brain that you gave me. Was it Hans Delbruck's?

Igor: [pause, then] No.

Dr. Frederick Frankenstein: Ah! Very good. Would you mind telling me whose brain I DID put in?

Igor: Then you won't be angry?

Dr. Frederick Frankenstein: I will NOT be angry.

Igor: Abby someone.

Dr. Frederick Frankenstein: [pause, then] Abby someone. Abby who?

Igor: Abby... Normal.

Dr. Frederick Frankenstein: [pause, then] Abby Normal?

Igor: I'm almost sure that was the name.

Dr. Frederick Frankenstein: [chuckles, then] Are you saying that I put an abnormal brain into a seven and a half foot long, fifty-four inch wide GORILLA?

[grabs Igor and starts throttling him]

Dr. Frederick Frankenstein: Is that what you're telling me?

[Copied from IMDb for convenience though I can pretty much recite the movie from memory for reasons we need not get into.]

Also, if you have the DVD, the Mexican interview with Gene and Cloris is worth watching to see Gene having fun.
