TV-Y7
S6 • E24 Aug 9, 2006As Billy, Mandy, Grim, and Irwin hang from a rope about to be eaten by a giant sea serpent, Irwin wonders how they came into that trouble. Billy and Grim each tell separate stories on how they originally became best friends forever and ever. Billy's fantastic story is about him and Mandy being space patrol officers who collect the Grim Reaper's bones, cloak, and skull to summon him; Grim tells a story on how the evil Mandy and his pet servant Billy managed to capture him inside a containment unit (parodying the Ghostbusters' ghost traps). Mandy quickly tells the real story, and footage from the first episode is seen, before the four are swallowed whole by the serpent.
