An instructor in chemical warfare asked soldiers in his class: "Anyone knows the formula for water?" "Sure. That's easy," said one man. "What is it?" "H, I, J, K, L, M, N, O." "What, what?" reasked the instructor. "H to O," explained the chemistry expert.

A man once insulted Chuck Norris by saying he was smarter than him. That man was Stephen Hawking.

Newton's 3rd Law never applies to Chuck Norris.

One day, a Mechanical Engineer, Electrical Engineer, Chemical Engineer and Computer Engineer were driving down the street in the same car. All of a sudden, the car broke down. The Mechanical Engineer said, "I think a rod broke." The Chemical Engineer said, "The way it sputtered at the end, I don't think it's getting gas." The Electrical Engineer said, "I think there was a spark and something is wrong with the electrical system." All three turned to the computer engineer and said, "What do you think?" The Computer Engineer said, "I think we should all get out and get back in."

Chuck Norris has proven Newton's third law of physics, there is no force equal to a Chuck Norris Roundhouse Kick.
