A test for being drunk
A police officer pulls over this guy who had been weaving in and out of the lanes.

He goes up to the guy's window and says, "Sir, I need you to blow into this breathalyzer tube."

The man says, "Sorry officer I can't do that. I am an asthmatic. If I do that I'll have a really bad asthma attack."

"Okay, fine. I need you to come down to the station to give a blood sample." "I can't do that either. I am a hemophiliac. If I do that, I'll bleed to death."

"Well, then we need a urine sample."

"I'm sorry officer I can't do that either. I am also a diabetic. If I do that I'll get really low blood sugar."

"Alright then I need you to come out here and walk this white line."

"I can't do that, officer."

"Why not?"

"Because I'm too drunk to do that!"

An Unusual Vet
There was once an aspiring veterinarian who put himself through veterinary school working nights as a taxidermist.
Upon graduation, he decided he could combine his two vocations to better serve the needs of his patients and their owners, while doubling his practice and, therefore, his income.

He opened his own offices with a shingle on the door saying, "Dr. Jones, Veterinary Medicine and Taxidermy -- Either way, you get your dog back!"
