We realize there's only so much time one can spend in a day watching new trailers, viral video clips, and shaky cell phone footage of people arguing on live television. This is why every day The Atlantic Wire highlights the videos that truly earn your five minutes (or less) of attention. Today: three teasers for the new season of Mad Men go heavy on the teasing, Sarah Palin is an enthusiastic supporter of Abraham Lincoln, and a look back at John Glenn's five hours in space.

AMC has released a new batch of teaser trailers for the upcoming fifth season of Mad Men. By this point, we've accepted the fact that Matthew Weiner plays his cards close to the vest, but even by his standards, not much is revealed. Jezebel notes that all the footage appears to be from last season. So what did we learn? Well, Roger Sterling is back. We know this because one of the three spots is called, "Roger Is Back." This could all be part of a slow reveal, letting audiences know which characters Weiner has deemed fit to bring back. In which case, we hope the next installment in the campaign is called "Chauncey Is Back." [Jezebel]



The Central Institute of Technology in Perth hired alums Henry Inglis and Aaron McCann -- an Australian comedy duo -- to make an ad for the school. Somewhat predictably, the result is strangely paced comedy gold of the Tim and Eric Awesome Show, Great Job! variety. The lesson, as always: Do not ask alums in the comedy business to design your school's ad campaign, unless you want it to go viral for reasons that have nothing to do with the stellar curriculum and three full-sized soccer fields.

50 years ago today, John Glenn orbited the earth three times in just under five hours. In the history of American days at the office, this was one of the more productive. [TheMercuryChannel]
