Ep 15. See You There

Mordecai and Rigby receive an invitation to go to a party hosted by their old college friends, the Party Horse 426, and the Unicorns. When the invitation arrives, they're thrilled and can't wait to attend the party, but soon realize they don't have anything to wear. Eileen offers to help them pick out outfits for the party, but they are unimpressed by her choices and decide to go shopping for clothes themselves.

As they shop for clothes, they come across a slick and stylish salesperson named Rich Steve, who offers them a deal on some flashy party clothes. Mordecai and Rigby are swayed by his charm and end up purchasing the clothes, not realizing that they've been cheated into buying cheap knockoffs.

When they arrive at the party, they quickly realize their mistake as they are the only ones wearing cheap knockoffs in a room full of high-quality designer clothes. Despite feeling embarrassed and out of place, they decide to make the most of the situation and try to fit in.

As the night goes on, they start to have a good time and even impress some of their old college friends with their dance moves. However, when Rich Steve shows up at the party, they realize that they've been scammed and confront him about it. Rich Steve admits to cheating them and tries to make a run for it, but Mordecai and Rigby chase him down and demand their money back.

In the end, they manage to get their money back and return the clothes. They may not have been the most stylish guests at the party, but they learned a valuable lesson about trusting their instincts and not falling for sales pitches that seem too good to be true. And they still manage to have a good time with their old friends.
