LUKE: Take it back.
LORELAI: Come on. Just the jacket. Just once, be too sexy for your shirt and do a little dance on the catwalk.
Lorelai is referring to the 1991 dance-pop song I’m Too Sexy, by British band Right Said Fred. The song includes the lines, “I’m too sexy for my shirt”, and “I do my little turn on the catwalk” (not a dance, as Lorelai seems to think).
Fun and cheeky, the song was a massive hit, and went to #1 in the US, Canada, Ireland, Australia, New Zealand, and Austria. It spent weeks at #2 in the UK, but was never able to crack #1 in its own country (Right Said Fred’s more sedate Deeply Dippy was a #1 hit in the UK instead).
I’m Too Sexy was included on Right Said Fred’s 1992 debut album Up. Depending on your point of view, it’s either one of the best songs of the 1990s, or one of the worst of all time.
