The Mathematician and the Squirrels

A mathematician lived alone in a little white house, near a tall oak tree.
On Tuesdays he ate tuna casserole.
Each day he spent 6.5 hours working on equations and theories.
On Sunday he went for a long walk and would try to identify every tree he would pass by.
When he went to work at the college, he only walked on streets that began with the letter "B".
One day he saw two gray squirrels chasing each other.
As they raced onto the street, they were both crushed by a large black moving van.
The driver did not seem notice he had taken the lives of these two squirrels.
Ironically, the gilded letters of the truck said, "Death Wish Piano Movers".
The mathematician was stunned.
He thought there must be a connection, but he couldn't be certain.

Sometimes simplicity breeds ambiguity.
