Joke of the day.

Jason has a conversation with his new neighbour Pete:

J: So what do you do?
P: I teach deducive logic.
J: Huh?
P: Let me demonstrate. Do you have a dog?
J: Yes.
P: From this I deduce that you have a family?
J: Yeah.
P: And a wife?
J: Yeah.
P: And if you have a wife, I deduce that you are heterosexual.
J: That's amazing!

After this Jason visits his friend Chris:
J: I just found out this awesome field called deducive logic.
C: Say what?
J: Let me demonstrate. Do you have a dog?
C: No.
J: Fag!
