I feel I should clarify the stupid jokes that I post. My favorite jokes have always been ones that I repeat over and over to different people and the more groan inducing the better.
*pulling up to train tracks* "Hey look, the train just went through...you can still see it's tracks"
*seeing a farmer out in the field "Hey look....now there is a man who's outstanding in his field"
*Seeing geese flying over in a V formation* "Hey, you see those geese up there? Did you know they fly in a V to lower wind resistance? You ever notice that one line is always longer than the other? You know why that is?" *Wait for some scientific guess that is assuredly coming* "No...it's because there are more geese in that line"
Those are my favorite types of jokes

I would have to say that my favorite joke of all time revolves around a Chinese gentleman applying to be a priest and one of the tests is to explain Easter. I won't bore you with the joke, but it ends with the lines "The rock ROLLS away on it's own.....Jesus steps out....sees his shadow....SIX MORE WEEK WINTER!!"
