Sup All?

One of the great elements of The Bob Newhart Show was in its subtle humor. Bob asks Carol to take a letter, and Jerry's there and he goes:

"Lots of luck if you want a letter typed by this bimbo.....See the "S on her keyboard doesn't work, so everytime you dictate any word with an "S" in it, she just makes up a new word!"

Carol: "That's gratitude, I busted my "S" typing your letters."

Bob starts dictating and Jerry joking replaces his words with a whole bunch of S-words! LOL!

(Something like this: )

Dear Sir,

I am shamed by the slip-shot service of your subordinate superior.

And Carol replaces it with,

Dear Guy,

I am annoyed by the boo-boo of your jerky helper! LOL!!!

What episode is this? Is this the same one where Carol says, "If you ever again refer to me as a bimbo-I will rip your spleen out."
