A big city doctor visits an Indian tribe full of men,
he asks “How do you guys relieve your s**ual tension?”
“Simple, just come down to the river tomorrow and we’ll show you.”
The next day the doctor shows up and sees a group of men near a donkey.
One man says “Since you’re our guest you get to go first.”
The doctor not wanting to go against custom starts to kiss,
then proceeds to have s** with the donkey.
Then a man in the group asks “Are you almost done Doc?”
“We need the donkey to cross the river in order to get to the tribe of women.”
