Major lyric problem!

Ok, I normally just read on here and keep my comments to a minimum, but I do have a question that's driving my roommates and me crazy! Sometimes when I hear a phrase, I'm like, "That's from a musical!" and go crazy til I figure out what one. Well, we have one of those phrases, and we can't figure this one out. The phrase is, "It gets old." delivered with a sarcastic tone, with sarcastic emphasis on the word "old." That may not be exactly what is said, but it's similar and is said with the same tone. For some reason I have an image of Idina saying it in the Rent or Wicked cast recording, but I'm not sure. Can any of you masters help us?! Thanks!

Well, scratch that, we finally figured it out. It's Gary Coleman on the Avenue Q recording. I think I was associating the tone it gets delivered with with the "She's my sister" from La Vie Boheme. Yeah, I know, those aren't similar at all, but oh well, at least we figured it out. Cheers!

Its from "It Sucks to Be Me" from avenue q. when gary coleman says "what you talkin about willis? it gets old!" it's a spoken line.
