A tribesman went to his village medicine man and requested a colonic for his constipation.
The medicine man said, “Let’s try something else first.”
He opened a jar and pulled out a dried out fern, placed it in a cup of hot water and told the man to let it brew a bit.
After a few minutes the medicine man said, “Here, sip it slowly.”
The man did and suddenly his eyes rolled back in his head, followed by the unmistakable sounds and smells of a wicked shit.
The medicine man smiled and said, “With fronds like these, who needs enemas?”
