Balko recalls the two shortest jokes he knows for a Reddit short jokes thread:
First…Masochist: Hurt me!Sadist: No.
And the second:
Pretentious? Moi?
(Actually, I believe I'm allowed to say the second one without being classified as pretentious, because I actually do speak French. Though, whether that is in itself a good enough reason to classify me as pretentious, is up for debate. =/)
