LORELAI: Well, we are not two wild and crazy guys.
Lorelai is referencing a series of sketches on comedy television show, Saturday Night Live. They feature the Festrunk Brothers, Yortuk (played by Dan Akroyd) and Georg (played by Steve Martin), who have emigrated to the US from Czechoslovakia. Culturally inept, they went to a variety of social venues (bars, dance clubs, art galleries) in an attempt to meet American women – who were invariably put off by their clumsy behaviour. Their catchphrase was, “We are two wild and crazy guys!”. The sketch debuted in 1977, and the last one was in 2013.
