Who on earth would find that funny???
Surely you have heard the joke, Like father like son. The dad probably reads Hustler so someone thought it would be funny to have the kid doing something that looked like what dad did.
It does not have to a pin up picture of a girl. People do the same thing dressing their kids up like adults, putting them in simulated adult situations.
The next thing you know we will be arresting people that take a picture of their kid with a beer in their hand or pretending to be working with a power tool (guess that would be someone claiming it promotes breaking of child labor laws).
This country has gone off the deep end.
Whether you find it funny or not is irrelevant. Post #27 was in response to Post #24 requesting it. No one forced you to click on the link. Get a life.
