MyLaffs Joke #2219
Four Irishmen are sitting in a pub. One asks the others if they know what is the fastest thing in the world.
The first replies: "It is blinking. Have you ever seen yourself blink? No. That's because it's so fast."
The second disagrees: "It is thinking. Before you know it there's a thought in your head it's so fast."
The third disagrees: "It is electricity. No sooner have you turned the switch and the light goes on."
The fourth (who asked the question) tells them: "You are all wrong. The fastest thing in the world is diarrhea. The other night before I could blink, think or turn the light on I'd filled my pants!"
