Not science related but I just remembered another oldy:
3 men line up to be executed by firing squad.
First man stands against the wall with his hands on his head and watches as the sergeant readies his men to aim. He looks to his side toward the smallish wall and thinks 'I'm not dieing without a fight.' Just before they shoot he points behind the men and shouts "TORNADO!!" the firing squad lower their rifles and turn around. The man legs it to the wall and dives over and gets away in the river.
The second man is lined up and watches as they take aim at him. Seeing what the first man did he decides to try it out. He looks upward and points shouting "UFO!!" again the firing squad lower their rifles and look up to the sky. The man runs to the wall, dives over and gets away into the river.
The third man is lined up by the now angry sergeant and then tells his men to take aim. Like the others he decides to try it out. Just before they're about to shoot he points forward and shouts "FIRE!!"
