That doesn’t add up…

By the way, I found a piece of land for my undersea watercraft.  
It’s a sub tract.

A Mathematician, a Biologist and a Physicist are sitting in a street cafe watching people going in and coming out of the house on the other side of the street. First they see two people going into the house. Time passes. After a while they notice three persons coming out of the house.

The Physicist: “The measurement wasn’t accurate.”.

The Biologists conclusion: “They have reproduced”.

The Mathematician: “If now exactly 1 person enters the house then it will be empty again.”

As the animals left the ark, Noah told them to go forth and multiply.

After some while, Noah happened upon two snakes sunning themselves. “Why aren’t you multiplying?” Noah asked. The snakes replied, “We can’t, we’re adders.”

So Noah and his sons went into the nearby forest and felled some trees. They made a platform of logs onto which they placed the snakes. You see, even adders can multiply using a log table.
