I guess that no one has any jokes for me. So I will tell you my favorite (appropriate) joke. I also have a few inappropriate jokes, but I will refrain from using those here.

Here is the joke (and you should imagine that it is told in an English accent, because that is how I heard it the first time):

There are two cows standing in a field. One cow turns to the other and says, "What do you think about this mad cow disease?"
The other cow says, "I'm not a cow, I'm a helicopter!"
