Bertram is looking at an old photo, taken in 1923, of the original employees of Sterling Cooper. With Roger and his nerd glasses looking over his shoulder, he waxes nostalgic about how psyched they all were, and then Roger notices that everyone in the photo is now dead except for Bertram and some guy named Doug Thomson, who apparently once let Roger eat an entire roll of laxatives in the mistaken belief that they were candies. "I want him to show up and keel over." Heh. Neither man is too jazzed about going to the party, although in Bertram's case, it's because it's a reminder that his expiration date in the business (and in life, no doubt) is drawing close, while Roger more pettily doesn't want to hear Don "accept an award for his humanity." Although it does sound somewhat revolting when you put it that way. Bertram takes the time to remind Roger that Don is important, but Roger goes on that he found Don, working at a fur company and going to night school, "and that girl, Betty. I remember Mona said they looked like they were on top of our wedding cake." It's nice when you don't even have to show up to be thought of as witty. Unlike Roger, however, Bertram is serious about not going to the party, and Roger tells him it's okay: "It's not like it's our company anymore anyway." He then shows Bertram another picture, that of a woman (probably a secretary, given that she's posing while on the phone), and asks Bertram if he remembers her, and Bertram gives an offhand "Hmph!" that I choose to interpret as "I'll tell you about her, but not until you turn sixty."
