Just ask the question

A cop pulled a guy over one night and said, “Sir, I need you to blow into this Breathalyzer.”

“I can’t do that,” he said. “I’m an asthmatic and it’ll give me an asthma attack.”

“Okay, then you need to come down to the station and have some blood drawn.”

“Nah, I can’t do that either; I’m a hemophiliac and I’d bleed to death.”

“Then I need a urine sample.”

“Well, I’m a diabetic, so my sugar would get really low and that’s dangerous.”

“Okay — then you need to step out of the car and walk down this white line.”

“I can’t do that either,” the man said.

“Why not?”

“Because I’m drunk.”
