Jim’s car is swerving all over the road so a cop pulls him over, “Step out of the car†says the cop, “I am going to need you to take a  breathalyzer test.†“I can’tâ€, Jim responds “You see I have very bad asthma, that can set off an attack.â€
“Alright,†says the cop, “then you’re going to have to take a blood test.†“Can’t do that either,†Jim responds, “I am a hemophiliac, if a wound is opened, I won’t stop bleeding, and I could bleed to death.â€
“Ok,†the cop answers “then I will need a urine sample.†“Sorry,†says Jim “I also have diabetes, that could push my sugar count really low.â€
“Fine, so just come on out, and walk a straight line for me.†“Can’t do that either†responds Jim. “Why not?†Demanded the exasperated cop. “Well, because I’m drunk!â€
