“The drummer in Spinal Tap”

RORY: I went out onto the patio.
LORELAI: Ugh, Rory, that’s like accepting the position as the drummer in Spinal Tap.

Spinal Tap is a fictional English heavy metal band created by American comedians and musicians Michael McKean, Christopher Guest, and Harry Shearer. They first appeared on a 1979 sketch comedy pilot called The TV Show, but are best known from the critically-acclaimed 1984 mockumentary film, This is Spinal Tap, considered one of the best films of the 1980s. The heavy metal fan and comedic Lorelai must surely love it.

Spinal Tap’s fictional history includes a succession of drummers, all of which have died in strange circumstances, such as a “bizarre gardening accident”, “choking on someone else’s vomit”, two suffering spontaneous combustion on stage, and one death a mystery police thought better to leave unsolved.

Lorelai’s saying that Rory was doomed the minute she went out on the patio.
