Jon Hamm

Actor Jon Hamm covers this month’s issue of Rolling Stone magazine. The well-endowed “Mad Men” star is a bit defensive about his impressive member that has launched Internet memes.

When asked about his predilection for walking around without underwear, he snapped: “They’re called ‘privates’ for a reason. I’m wearing pants, for f*ck’s sake. Lay off.”

From Holly Scoop:

When asked if he was aware of his Internet meme-status penis, Hamm replies, “Yeah, I’m familiar.”

“Most of it’s tongue-in-cheek, but it is a little rude. It just speaks to a broader freedom that people feel like they have — a prurience,” the actor says.

As we previously reported, Hamm’s endowment has become such a hot topic that he was supposedly ordered by AMC execs to, in fact, wear underwear due to the new season’s increasingly fitted wardrobe.

“This season takes place in the 1960s, where the pants are very tight and leave little to the imagination,” a source on the show said. “Jon’s impressive anatomy is so distracting that they politely insisted on underwear.”

Hamm ends the penis chat with a cry for action, telling people enough is enough already.

“They’re called ‘privates’ for a reason. I’m wearing pants, for f*ck’s sake,” he says. “Lay off.”
