Meh. The Klingons are vastly overrated and their appeal escapes me.
I once had a big tall guy dressed as a Klingon come up to little ole 5-6 me and say something that sounded threatening in "Klingon."
Too bad for him I know about ten words of "Romulan." After I answered him back (standing right up in the personal space of someone bigger than I is no problem,) he said "What language was that?"
"Romulan," I said proudly. "Have a nice day!"
He was at a loss for words.
My idea of fun at a Star Trek convention is to walk past a group of Klingons and shout "Long Live Romulus!"
The things I hear in return!
