Exhausted, happy. I made about half of my lines, and winged the rest. In Klingon, or some sort of Klingon-esque sounds. I probably insulted somebody's chihuahua, but made it through, and we got a standing ovation.
Some day there will be stories of the insanity that was a Klingon Christmas Carol, but the down-and-dirty of it is that we had a really good crew of people working their asses off for a show, and people enjoyed it.
And I made it through the line from hell.
Now I have to figure out whether I should shave the rest of my moustache off.
