YMMV / Regular Show S 06 E 09 White Elephant Gift Exchange

• Alternative Character Interpretation: Some fans theorize that Muscle Man intentionally kept opening his prank Christmas gift(s) as a means to atone for mistreating his friends, given how even Pops and High-Five Ghost were in on it.
• Catharsis Factor: Those who loathe Muscle Man will more than enjoy the ending where the trap in the Christmas gift for him is sprung and he gets put through a massive Humiliation Conga. The cherry on top is seeing Benson and the others look on gleefully, with Rigby recording it for further revenge.
  Skips: Now this is fun!
