When Jake is driving Andrew to Melanie at the battlesite, Jake is driving with the truck in the park position.
During the film's original outdoor reception Jake carries Melanie, who feigns death after having supposedly been struck by a lightening bolt, towards the wedding guests. Jake announces, "Melanie Carmichael is dead" but then a few seconds later he says, "Long live Felony Melanie." Jake and Melanie do this as a practical joke. The reaction of Melanie's mother at the supposed death of her daughter apparently upset the test audiences so much, that the production crew reshot the whole reception scene, minus the practical joke.
