There is this guy at my club who said to my friends, I have the intellect of an artichoke.
Even though it's true to some extent, it wasn't a nice thing to say about a fellow member.
In the club championship this year, he lost by one stroke by missing a three foot putt on the final hole.
The look on his face was hilarious, his eyes suddenly went wide in horror and his jaw dropped. I controlled myself, but Lord it was funny.
The phenomenon is called schadenfreude; that is to laugh or derive amusement by contemplating the misfortunes of others, in particular one's "enemies." Some say it's a sick form of humour, but I've yet to meet someone who isn't guilty of it from time to time. Why is it improper to laugh at the cruddy strokes of other players? Because only jerks do that? Because I would not, after my pitiful shots, appreciate being laughed at (do not do unto others what you would not have done onto yourself by others)?
