A big-city doctor visits an Indian tribe full of men, he asks,
“How do you guys relieve your s*xual 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*x 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.”
