- The Alternate Universe edition of the Star Trek Customizable Card Game includes a Paul Rice card with "daed si luap" written on it; as "Daed si luap" is a letter-for-letter reversal of "Paul is dead", this is intended as a playful reference to the urban legend that McCartney actually died in 1966, and the Beatles hid clues in their later work, many of which could be found by playing songs backwards.
