Well we guess there's no polite way to phrase this; apparently Jon Hamm has a very big willy. So much so, he was asked never to go commando on the set of Mad Men 3 as his "impressive anatomy" was causing quite the bit of excitement among the team.

While many of you will now just be thinking about Don Draper's ding dong, what we're wondering is why he'd be sauntering around without his underwear on in the first place. Apparently, it has something to do with the tight outfits he's required to wear on set. Without a pair of longjohns to keep everything nicely packaged, the resulting freedom of his man bits were "leaving little to the imagination".

Speaking to the New York Daily News, a source from the set revealed: "This season takes place in the 1960s, where the pants are very tight and leave little to the imagination... Jon's impressive anatomy is so distracting that they politely insisted on underwear."

Well there you have it; what will Michael (big mickey) Fassbender have to say about this? Is another hot-shot actor about to rob him of his title? We just know you clever entertainment.ie readers will have puns coming out of your ears relating to this news; so let's hear 'em.
