Hmm, I'm American, so there are plenty of those references. But I'm of Indian origins. There are a few jokes about Jonathan. I'll take that as a reference. Or when Liz mispronounces Ananda. She made it Indian sounding when the girl's name was plain old Amanda.
Alec's joke...he made fun of Russians too. And mostly, he was making fun of himself: his age and how desparate he is.
