Friend 1: "*crying hysterically*"

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't," Jim responds. "You see, I have very bad asthma, that can set off an attack." "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." "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." "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!"
