Borrowed jokes?

[on:]

So, I was watching an old episode of M*A*S*H just now, and heard used basically the same gag from Futurama's Anthology of Interest I:

"Blackmail is such an ugly word.  We prefer extortion." - leaving off the "the x makes it sound cool," though.

Clearly, the Futurama staff borrowed the gag from this classic series.  I was wondering if anyone else had noticed similar echoes of other media in our show, beyond more general parodies and references (the above line: borrowed gag.  The iHawk robot: parody/reference.)

Holy crap, I'm posting in on-topic.

When Farnsworth says "Leela you ignorant dope" it reminds me of when Dan Aykroyd used to say "Jane you ignorant slut" on the original SNL

I've seen the joke about some-one being born in a queue a few times on Tv
