Did you know the Hebrew word for "know" is "yadah?" Brian wants to know if Seinfeld's yadda-yadda-yadda is a phrase that's come out of the Jewish culture's knowledge of Hebrew.
Like when Elaine said something to the effect of, "So I met this guy, and we ended up back at his apartment, and yadda-yadda-yadda, and the next morning we..." George calls her on it and says, "Wait a minute! You can't yadda-yadda-yadda sex!" In this context yadda-yadda-yadda means, "well, you know." "We ended up back at his apartment, and well...you know...and the next morning..."
Know. Yadda. Sounds like a lazy pronunciation of yadah to me. It's at least interesting to consider. I'm such a nerd. But Brian started it!
Anyone know for sure?
