An old owl was perched on a tree on top of a hill one very cold night:
He looked down in the valley and saw a light in a window so he decided to fly down to the window ledge in hopes there was some warmth escaping.
Well sure enough it was warm, so he fell fast asleep.
He didn’t know that there were two vetenary students inside studying for final exams.
The two vetenary students spotted the owl and decided to use him as practice.
They eased the window open and gassed him.
The first student looked down the owls throat and said he has tonsillitis, so he operated.
The other looked at his butt and announced that the owl had hemorrhoids, so he operated.
They placed the owl back out on the ledge.
The owl woke up very groggy and flew away.
The next winter that same owl was perched on the same tree on a very cold night.
A young owl landed next to him and said brrrr it sure is cold out tonight.
The old owl agreed.
The young owl noticed there was a light down in the valley and suggested they both fly down there to the window ledge and maybe find some escaping heat.
The old owl replied.
“No way. Last year I did the same thing, passed out, woke up drunk and for the next six weeks I couldn’t sh!t worth a hoot or hoot worth a sh!t.”
