Don asks if this fur will be for his mother, and Roger answers, "I bet you never hear that," which isn't exactly a "yes." Don asks if he'd like to throw out a ballpark figure, but Roger isn't sure, adding that he needs to spend a lot without appearing to spend too much, which Don says is hardly a unique problem. Offering an apology if he's being too forward, Don asks if the fur is to say sorry for something, but Roger denies that, "No, no, no. I know exactly how much that costs." Heh. He adds that he needs something that says "I'm getting to know you, but I don't want to scare you," which pretty much puts paid to the idea that it's for his mother even if Don is uncharacteristically naïve, and this to Don means a mink stole, which has the advantage of, you know, being mink, but is always the right size and is a nice way to ease into things. "You can always come back for the rest of it."
Roger, who's hilariously been trying the thing on, suggests they split the difference and go for a waist-length number before catching sight of the store's poster, which has the slogan "Why wait for a man to buy you a fur coat," with a picture of, I do believe, Betty Hofstadt (Draper? Not sure of the timeline here). Roger opines that the copy is "dumb," and asks who does their work, and Don, unfazed by the insult, replies that he does -- he told the owners writing copy was a hobby of his, and they let him try his hand at it. Roger hands Don his card, and Don, encouraged, asks if he can give him a call, but Roger, after telling him that the store needs twenty of the posters to be effective, says he only wants Don to ring for the delivery instructions for the stole. Don takes this in stride...
...and later, Joan, dressed in a sexy little number with loose shoulder-length hair, is calling to him from within their hotel suite that she saw him leave the office with something under his arm. I'm guessing it wasn't a bottle if she's making note of it. Roger emerges from the other room with a large box, and when Joan opens it and puts the mink jacket therein on, she's thrilled, and she certainly seems to have been far less hard-boiled at this age. However, Roger notices something else in the box -- a leather binder, which he opens to find a Noah's Ark-themed sketch for a Play-Doh ad.
Roger does not appreciate Don's opportunism, but quickly forgets about it as Joan, after an obligatory protest about how the gift might be too much, gets amorous; referring to the jacket, she breathes, "When I wear it, I'll think of everything that happened the night I got it." Well, so far he came out with a box, and then...oh, that's not what you were referring to. Carry on, preferably offscreen. Roger then comes back to himself and barks for Caroline to get in there. "I think I finally have a work story!" I hope Caroline gets hardship pay.
