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 an 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."
"All right then I need you to come out here and walk this white line."
"I can"t do that, officer."
"Because I"m too drunk to do that!"
A dog"s sense of smell is one of the keenest in nature. If a pot of stew was cooking on a stove, a human would smell the stew, while the dog could smell the beef, carrots, peas, potatoes, spices, and all the other individual ingredients in the stew.
