Ep 15. Bachelor Party! Zingo!

Mordecai and Rigby plan a bachelor party for their good friend and coworker, Muscle Man. They want to make sure the party is one for the books, so they call on the help of the one and only Skips to help them plan the perfect celebration. However, their plans are quickly derailed when they learn that Muscle Man has already hired a party planner named Zingo.

Initially, Mordecai and Rigby are skeptical of Zingo's abilities and are sure that they can throw a better party themselves. However, as they start to witness Zingo's preparations for the big day, they begin to second-guess themselves. From the extravagant decorations to the impressive entertainment, Zingo seems to have everything under control.

Despite their doubts, Mordecai and Rigby still want to contribute to the party in some way. They decide to create a special drink for the bachelor party - a concoction made from several different types of energy drinks. The duo spends the rest of the day sampling various energy drinks and mixing them together, trying to find the perfect combination.

As the night progresses, the party starts to take a turn for the worse. The energy drink concoction is too powerful, and partygoers start getting sick. Meanwhile, Muscle Man is having second thoughts about his upcoming marriage and starts questioning whether he's making the right decision.

Thankfully, Skips steps in to save the day. Using his wisdom and years of experience, he helps Muscle Man talk through his fears and doubts, and ultimately convinces him that he's ready to take the plunge.

In the end, the party turns out to be a success, albeit in a different way than Mordecai and Rigby had initially imagined. Muscle Man is able to put his fears to rest and proceeds with his wedding plans, while Mordecai and Rigby learn an important lesson about the value of teamwork and delegation. The episode ends on a high note, with the gang celebrating into the night and Muscle Man feeling confident and excited about his upcoming marriage.
