So, I've only been telling people that know of Seinfeld that my trip was actually Milan to Minsk. My Euro friends (and American friends with less-than-ideal taste in TV) only hear about the BB (Baltics and Belarus) bit. A few have found out the true itinerary, and the question invariably is, "why are you going to Milan if you're going to the Baltics & Belarus". The answer, of course, is that I have too much free time on my hands.
The more complete answer is that the TV show Seinfeld referenced a fake movie, "Rochelle, Rochelle: A Young Girl's Erotic Journey From Milan to Minsk" in a few episodes. We never see it, and only hear a few lines of dialogue and a bit of a song from the Broadway musical adaptation (starring Bette Midler!). It's a cheesy Skinemax-style flick that enthralls the men and mystifies Elaine. Obviously, this is a strong basis for a vacation. Maybe next time I'll retrace Indy's trip in "The Last Crusade"*.
Next up: What will JT have to do to get a visa?
* Venice-Berlin-Petra. I'd skip the USA bit because it's never mentioned where he's a professor
