Newman Jokes

I got this message detailing a first day of class experience from a

for Newman Hall- and, I thought i'd found it. no sign- no main
entrance.
So I walk around the building and find what I perceive to be an acutal

Two guys in white overcoats.
A cow. Upside-down with hooves pointing into the air.
On some type of cart.
A chainsaw.

who was not facing me.) And I shut the door.
