"Scientists game of Hide and Seek" joke

One day all the scientists in heaven decided to play hide-n-seek. Einstein was "it" and had to count up to 100 and then start searching.

Einstein starts counting... "1,2,3..."

Everyone starts hiding except Newton who just draws a square of 1 meter and stands in it right in front of Einstein.

"97,98,99... 100!" He opens his eyes and finds Newton standing in front.

Einstein immediately sees him and starts yelling, "Newton's out! Newton's out!"

Newton denies and says, "I am not out. I am not Newton."

All the scientists come out to see how he proves that he is not Newton.

Newton says "I am standing in a square of area 1m squared. That makes me Newton per meter squared since one Newton per meter squared is one Pascal, I'm Pascal. Therefore, Pascal is OUT!"
