Whenever I’m down, I like to watch this:
Yes, this is Captain Kirk fighting Gorn, the needle-toothed, shoulder-gnawing, boulder-throwing bipedal reptilian wrestler with the BeDazzled eye sockets and tres chic copper-and-gold lamé halter-neck shorterall ensemble.*
The first time I watched this scene, I almost broke. I laughed until I cried, and then kept laughing until I was physically in pain, yet I could not stop.
(Many, many) repeat viewings have helped me to build up some slight immunity, but not much. This clip will never not be hilarious.
