Here's a funny joke circulating on the internet that I hadn't seen before.
A man and his wife were watching a television program on psychology, and the subject being covered was mixed emotions. The wife was fascinated with the subject, but as the program wore on, the husband became more and more frustrated. Finally he had had enough of the banality.
"This program is bullsh*t! There is no way you can be extremely happy and incredibly sad at the same time!"
His wife replied that she thought it definitely was possible.
He replied "I bet you a hundred dollars that you can't possibly say anything that would make me happy and sad at the same time!"
The wife thought a minute and said "You have a bigger penis than any of your friends."
