A pennyless hobo was walking thestreets when he saw a sign "Blood Donors Wanted 10 per Pint" So he went in and said "Take 10pints out of me" The Nurse said Sorry we can only take 2 pints at a time . After taking the 2 pints she gave him 20. The hobo went off , further down the street he saw a sign "Sperm Donors Wanted 50 a shot" so he joined at the back of a very long line. Just then a woman with bulging cheeks and a tightly closed mouth joined the line. The Hobo turned to and said "Hey miss this isn't the bus stop you know, and she nodded.
