I trust everyone has lolled about this already?
Turns out he wasn't the first to derive humor from drawing a penis, can you spot the hidden Phallic image in this one?
The one below is rather terrifying, and if it's drawn from real life then the model should perhaps go into porn or become a sideshow attraction
But these all pale in comparison to the original "not to scale" penis drawings modelled here by Doug of Larkin Fame and Neil of Campesinos Fame from back in the day.
(Note the careful detail and artistic ingenuity which went into the drawings)
