The Meme of the 6th Level
Bob has reached the top of the meme hierarchy with his 6th level joke:
Why did the chicken go to the doctor?
Because it had Poultry Fowl Play!
This meme has reached the peak of absurdity and will soon collapse under its own weight.
Next level of meme, coming soon...
Go back to the 5th level, if you dare
