Need help with a Bob Newhart joke

I want to say the joke is from one of his albums, but I’m not sure.

Newhart is explaining something, then realizes he may have offended certain people in the audience, so he says he didn’t mean to be condescending. Then he explains that “condescending means talk down to.”

Or something like that.

Anybody remember where this is from, before I download his albums?

Gah, nevermind my Google-fu was weak.

Asked and answered.

S’okay, anything that reminds us of the great Bob’s wit and talent is okay with me. I was just recounting the Eggs Benedict exchange for my family last night.

Bob’s in bed, sick. Emily offers to get him something.
B: Some eggs?
E: You got it.
B: Um, soft-boiled?
E: Okay.
B: On English muffins?
E: Sure.
B: With some ham?
E: Okay…
B: and a little hollandaise?
E: (pause) Bob, that’s Eggs Benedict.
B: It is?
