99 Words About … The madness of ‘Mad Men’s’ creator

“Mad Men” will return as mysterious as ever.

Jon Hamm’s penis has gotten so big — no pun intended — it has a half-dozen Twitter accounts.

This is what happens when the press can’t talk about “Mad Men” (9 p.m. Sunday, AMC).

Each season, Matthew Weiner, its spoiler-phobic creator, hilariously declares certain facts off-limits.

“The year the season begins” is always one. Like it’s ever going to be, say, post-apocalyptic 2273.

This year’s best: “Whether the agency has expanded to an additional floor.”

Seriously.

What type of fan cares whether Don, Roger, Pete and Joan will/won’t be walking up a staircase?

Probably the kind who’s busy tweeting Hamm’s privates.
