LD's talking like dukar is some super-rad thing that's sweeping the nation. I have a sister who used to do that after she said the word "strog-noff" as a mispronunciation of "stroginov". She thought it was funny, and started talking about proper usage of it, the history, and so ona and so forth. She also acted like it was some hilarious in-joke that everyone was in on. Eventually I was just like, "Seriously. It's not funny anymore, and it wasn't even in the first place." Obviously, this doesn't seem to be the case with dukar, but it reminded me.
By the way, I remember when I just assumed dukar was some Homestar Runner reference, since everything was back then.
