A woman yells out, "No, I won't sleep with you tonight, you pig!" Everyone in the bar stops and stares. Completely embarrassed, the guy slinks back to his table with a red face.
After a few minutes, the woman walks over to him and apologizes. She smiles and says, "I'm sorry if I embarrassed you. I'm a graduate student in psychology, and I'm studying how people respond to embarrassing public situations."
To which the guy responds as loudly as possible, "What do you mean $200 for a blowjob?"
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?"
