From the pages of Playboy advisor:

Q - My girlfriend asked why me save all their back issues of Playboy. I told her that every guy, growing up, had a friend whose father had a stash. The friend would share this bounty with his buddies -- a rite of passage. I'm saving my issues so that my future kid will someday be that well-connected friend.

A - Keep in mind that it won't be any fun for your son unless you "hide" them at the bottom of your sock drawer. And you thought your friend's dad was so dumb.

It's more embarrassing if your grandkids find your stash.... as is the case with BOTH of my grandads :P
