This episode came from the same taping as
Show No. 426 (2003). In "Greatest Hits", Colin said "Hi, we'll be right back to "Humpty Dumpty: The Early Years", in just a second.", which caused both to chuckle. This is because
Show No. 426 (2003) contained a similar play on a nursery rhyme title when Colin said "We're watching animal porn... "Mary Had a Little Lamb"... we'll be right back, in just a second."
