A cop pulls a guy over one night for swerving in and out of lanes on the highway. He tells the guy to blow into a breathalyzer. "I can't do that, officer, I'm an asthmatic. I could get an asthma attack if I blow into that tube."
"OK, we'll just get a urine sample down at the station." "Can't do that either, officer. I'm a diabetic. I could get low blood sugar if I pee in a cup."
"Alright, we'll take a blood sample." "Can't do that either, officer. I'm a hemophiliac. If I give blood, I could die."
"Fine then, just walk this white line." "Can't do that either, officer." "Why not?"
Mr. & Mrs. Johnson are at the bank when an armed robber bursts in. Realizing he forgot his mask, the robber makes everyone lie face down and warns them not to look at him or he'll shoot.
Sure enough one stupid customer sneaks a look, and BAM! the robber shoots him on the spot. The robber then asks if anyone else had seen his face.
Johnson, continuing to gaze intently at the floor, shouts out "I think my wife got a glimpse."
