The running time difference in total sums up to approx. 15 minutes (w/o ending credits), about 10 of those are made up of big and important differences. These are mostly alternative scenes, the smaller differences in contrast are usually one or more added sentences. The new scenes add to the movie's quality and make it even more funny than it initially was already. Good examples for this are the scenes with the couple asking the Fosters for money or the ones in the subway.
