Everyone gets cornered at family and friends gatherings and subjected to jokes but when someone finds out what I do for a living all of a sudden it becomes The Last Comic Standing.
But I do enjoy the occassional one word joke and it's usually bearable enough to get through. None of this, "So a rabbi, a foot-massanger and a penguin go into a bar" stuff. No, the one word joke gets straight to the punch. The good people of The Trinidadian Ministry of Computers tell a good one word joke with the help of visual aids. All you need to do is type in the word sauerkraut.
The only other one word jokes I know is apparatus and (the much less funny) hibachi (as in, My ass feels like a hibachi.). Yak is not a one word joke.
