Years ago my brother and I were smoking hash (I don't do it anymore)...

Me: " You know why I don't like smoking up? Because every time I do, I just tell bad joke after bad joke and I become a giant pain in the a$$ to everyone around me."

Bro: "So in other words, it has no effect on you at all."

Stoned, we both hit the floor laughing uncontrollably for about 5 minutes.
