I just found one tonight. I didn't realize where is stolen it from, but in the episode Bender Gets Made, this (paraphrased) conversation happens between Leela and the doctor:

What do you see here?

A greyish blob?

Yes! And this one?

A greyish blob?

Not... As right...

I've been saying, "Not... As [blank]" in similar conversations for years, and forgetting where I got it from.
