Obviously, his name, being so similar to the four-letter word, becomes one of the movie's ongoing jokes. As you can see, the man did not leave the best first impression on his girlfriend's family. Somehow, though, Focker comes out on top in the end. Like every romantic comedy, the ending is a happy one. To make the movie a little bit more enjoyable, there are a couple of sentimental moments that surface in the plot, like when Jack reads a poem about his dead mother and when Focker pours his heart out to Pam.
Comedy definitely steals the show, nonetheless.
Stiller acted his usual comedic part, but he would not have looked as good as he did if the other cast members did not pitch in.
