i'm a bit late to the 'Mad Men' party but i've been watching it on Neflix and in season 5 episode 8 there's a major DS reference...
Don Draper's wife Megan is an aspiring actress auditioning for soap operas. there's a scene of her reading scripts with a friend and although they don't say it by name she's reading about "Burke Devlin" and "Victoria" and some other 1966 references. for the record she thinks it sounds "silly' and gets a part on a more traditional soap.
