Watch the episode where they give you the answers to the show they did with the mistakes (April Fools Episode.)

In the opening credits where everyone is getting money out of the ATM and dancing off in pairs, Mimi usually comes from the right to spin another girl off of Mr. Wick's arm. But, in the mistake show, she came from the left. In the answer episode where they point out all of the mistakes, they didn't point that one out.
