Over the years 30 Rock has made a nice habit of including references to the city it is set in and films in. Sometimes, we get a long riff on something like the drunks on St. Patrick's Day and sometimes the reference will be a nice grace note. Like last night's reference to the random things you find on the G Train. Because yes, in the magical world of 30 Rock, a young Tracy Jordan not only took the G, but found a Buck Rogers decoder ring on the G's floor in the 70s. And then he shoved it up his nose, where it stayed for 30 years.

Wait, why did Jordan shove the ring up his nose? Because, he explains, "I knew if my foster mom saw it she would make me sell it at a pawn shop to get our family a Cheerio" (to which Liz Lemon reasonably responds, "Okay, sometimes I think the stories of your childhood poverty are exaggerated"). You can watch the pertinent scene below. Meanwhile, what interesting things have you found on the G train? We hope you didn't put it up your nose!
