International Joke Day Jokes - for smart people
July the 1st is International Joke Day! Are you smart enogh to get these Jokes?
1. A mathematician and an engineer decided they'd take part in an experiment.
They were both put in a room and at the other end was a naked woman on a bed. The experimenter said that every 30 seconds they could travel half the distance between themselves and the woman.
The mathematician stormed off, calling it pointless. The engineer was still in.
The mathematician said, "Don't you see? You'll never get close enough to actually reach her."
The engineer replied, "So? I'll be close enough for all practical purposes."
2. Einstein, Newton, and Pascal are playing a rousing game of hide and seek.
Einstein begins to count to 10. Pascal runs and hides. Newton draws a one-meter by one-meter square in the ground in front of Einstein then stands in the middle of it.
Einstein reaches 10, uncovers his eyes, and exclaims "Newton! I found you! You're it!"
Newton replies, "You didn't find me. You found a Newton over a square meter. You found Pascal!"
3. A Buddhist monk approaches a burger food truck and says, 'Make me one with everything."
The Buddhist monk pays with a $20 bill, which the vendor takes, puts in his cash box, and closes the lid.
"Where's my change?" the monk asks.
The vendor replies, "Change comes from within."
4. A linguistics professor says during a lecture that, 'In English, a double negative forms a positive. But in some languages, such as Russian, a double negative is still a negative. However, in no language in the world can a double positive form a negative.'
But then a voice from the back of the room piped up, "Yeah, right."
5. Noam Chomsky, Kurt Godel, and Werner Heisenberg walk into a bar.
Heisenberg turns to the others and says, "Obviously this is a joke, but how can we tell if it's funny?"
Godel replies, "We can't know that because we're inside the joke."
Chomsky says, "Of course it's funny, you're just telling it wrong."
6. The Laws of Thermodynamics are simple.
