Ep 11. Quips / Caveman

Mordecai and Rigby are back with another adventure in Regular Show season 5 episode 11, titled "Quips / Caveman". The episode is divided into two stories, each focusing on one of the two main characters.

In the first story, "Quips", Mordecai competes against a fellow park employee, Doug, in a battle of wits. Doug is known for his quick and biting insults, or "quips", and Mordecai wants to prove that he's just as good at the game. He enlists Rigby's help in coming up with insults, but quickly realizes that Doug is a tough competitor.

As the two escalate their insults, things start to get out of hand. They insult each other's mothers, ex-girlfriends, and personal appearance. The rest of the park employees gather around to watch the battle, but soon become uncomfortable with the harshness of the insults. Mordecai starts to feel guilty for what they're doing, and eventually learns an important lesson about the line between friendly banter and hurtful insults.

In the second story, "Caveman", Rigby discovers a fossilized caveman in the park and convinces Mordecai to help him reanimate it using the park's time machine. When they bring the caveman back to life, they discover that he's extremely primitive and doesn't understand anything about modern society. They take him on a tour of the park, but he causes chaos and destruction everywhere he goes.

Rigby starts to feel guilty about what they've done, and realizes that they should have left the caveman in the past where he belongs. But when they try to send him back in time, they discover that the time machine has malfunctioned and can't send him back. The caveman starts to enjoy his new life with Mordecai and Rigby, but they soon realize that they need to find a way to fix the time machine before things get even more out of control.

Overall, "Quips / Caveman" is a classic Regular Show episode that combines humor, heart, and some good old-fashioned hijinks. Mordecai and Rigby are at their best, getting into trouble and learning important life lessons along the way. Fans of the show won't want to miss this one!
