We’re less than 12 hours away from the season five premiere of “Mad Men.” That means there’s still a little time for Don Draper prognosticators to make their predictions about what’s in store for the team at Sterling Cooper Draper Pryce during tonight’s episode, airing at 9 p.m. ET on AMC.

Follow along with Sally Quinn and Ben Bradlee at the Washington Post’s Mad Men liveblog.

If you’ve managed to remain mostly spoiler-free, per “Mad Men” executive producer Matthew Weiner’s wishes, please share your best guesses about what will happen in tonight’s two-hour installment by posting a comment below. I’ll share some of the more accurate and compelling forecasts during Monday’s “Mad Men” discussion at 11 a.m. ET. (A post-episode analysis also will be published in Celebritology tonight for those seeking immediate “Mad Men”-dissection gratification.)

Need some assistance focusing your hypotheses for the premiere? Try setting an over/under on these matters.

— Number of times Don Draper will have sex. Remember: this is a two-hour episode.

— Number of alcoholic beverages Roger Sterling will consume. I reiterate: two-hour episode.

— Instances of Peggy feeling unappreciated at the office. This usually occurs at least once per hour, so you do the math.

—Level of Pete Campbell irritation. This metric can be determined two ways: either by the number of times Pete gets irritated by office politics, or by the number of times that you, as a viewer, get irritated by Pete Campbell.

—Narrative developments that relate directly to the sociocultural changes of the 1960s and their impact on our gang of heavy smoking white males. Hint: there will be at least one of these. And like all things “Mad Men,” it will inevitably inspire roughly 8,000 media commentaries and essays about the deeper meanings of Matthew Weiner’s retro creation.
