It was a normal day at the local sperm bank, when all of a sudden, a man bursts in with a mask a and a handgun and yells "EVERYONE! ON THE GROUND!"
Once every person in the facility is lying down, he walks over to the refrigerator area for very-recent donations, then turns around, facing the main area again. He points his gun at one of the nurses and shouts "You! Come over here, and open this door." She walks over, trembling profusely, and keys in the number on the door. The gunman say "Alright, grab a tray of the most recent donations and bring them to the nearest desk" After the panicking nurse does so, he makes one further demand: "Drink up!"
"E-e-Excuse me?"
"These are today's donations, right? Well, open up one of the tubes, and drink it!"
Still shaking, she takes off the lid of the tube, and pours it down her throat.
"Again."
She slowly opens another one, and repeats the action, shivering.
"A third time. Don't hesitate"
The nurse hurriedly does it again. The gunman takes of his mask and says "See Honey? It's not that hard now, is it?"
