For the love of nerds...

My dad told me this joke the other day, and I thought so highly of it I decided to put it on this majestic pedestal that is my blog. Hope you enjoy! Nerdy jokes are the best because it's like an inside joke with all the smart people in the world!

A biologist, a physicist, and a mathematician form a surveillance team and begin watching a house they believe to be empty. After a short while, 2 people go into the house.  A while later, 3 people leave the house.  The biologist says, "Look, they reproduced!"  The physicist says, "There must have been an error in the measurement."  The mathematician says, "If one more person enters the house, then the house will be empty again."
