Here's how the wedding goes:

Once upon a time, the husband and wife are getting married indoors, with some people gathered around them. The person says "You may kiss the bride." But, once the husband is so close to kissing his wife, he sneezes all over the wife, making the same sneezing-farting-burping noises as Kevin James did in Grown Ups 1 and 2. "THE WEDDING IS OFF!" the wife says. The husband does his stupid Kevin James warcry, spinning his arms, and lands face first into the 3rd layer of the fountain wedding cake on the table. Everyone applauds like in Balls of Fury. It turns out that the husband is Kevin James overall, and the wife is the same girl that he married in Mall Cop and Mall Cop 2 himself.

THE END!
