Insanity: Doing the same thing over and over again and expecting different results. that is how Albert Einstein defined insanity

Well, By observing someone won't say his name I was able to prove that Einstein was wrong


the someone said a joke for the first time and as a result of it he got a lough 


the same guy said the same joke after a while and as a result of that he got smile  


after a week or so, the same guy said the same joke for the third time so this time he got a totally different result, he got a look that meant "SHUT UP YOU MISERABLE BORING CREATURE"

Ok I know that was too much to extract from a look but I really read this out of the other guy's eyes

and no, I am not the one who gave him the look

Back to Einstein

he was a great Scientist, but he never knew that guy (who can't say the joke once).
