Fall Out Boy payed homage to 'This Is Spinal Tap' during their performance of 'My Songs Know What You Did In The Dark' on Conan.

The performance was complete with malfunctioning space pods (similar to when Derek Smalls was trapped on 'Rock and Roll Creation'), a Stonehenge monument on stage, and Derek Smalls himself (Harry Shearer made an appearance).
