Roger, dressed up as Krispy Kreme McDonald, says to Steve "I just saw a million faces, and I rocked them all." This is an adapted line from the Bon Jovi song "Wanted Dead or Alive" (which says "I've seen a million faces..." instead of "I just saw...").
Roger's character, Krispy Kreme McDonald, resembles Harry Shearer's character Derek Smalls in the movie This is Spinal Tap.

The end of the episode is a reference to the ending of The Sound of Music.
