X'D I had to read that through twice before I got it!!!
okay so these two guys are walking through a construction site, and one man says "I bet you can't throw up a smartie and catch it in your mouth." To which the other man replied "of course I can't, if I throw it up, it won't come down" To which the other man replied "It will, let me show you." And so he walks over to a brickyard, grabs a brick, throws it up. Lo and behold, the brick floats up and away.
Okay I got a better one.
This man and his duck want to go to Africa. The man can't take his duck on the plane, so he instructs it to land on the wing and fly. So in the middle of the flight, the pilot says there will be turbulence, so the duck is shook off. He's flapping his wings, he's working his ass off, and the man is screaming and cheering him on. The duck makes it. Later on, the pilot announces turbulence again. So the duck is shook off. He's flapping his wings, he's flapping them, and then the duck gets hit by a brick!
It's funnier if I say it out loud. I forget all the rest.
