When Greg (Ben Stiller Ben Stiller) is ready to propose to his girlfriend Pamela (Teri Polo Terry Paul) who has been in love for many years, he is surprised to learn whether the proposal is successful or not, not only through the beauty, but also through the father-in-law. Gregor and Pamela will go home to attend the wedding when Pamela's sister is getting married next week. The young man thought that this was a good time to please his future father-in-law and take care of his father-in-law. Greg's name is easily understood as "gay intercourse" in American. With such a strange name, it is destined that Greg's visit to his future father-in-law will not be as smooth as he expected. Sure enough, when they arrived at Pamela's house, Greg was gentle, but when he tried to be humorous when he was always interrupting, the face of his future father-in-law (played by Robert de Niro Robert De Niro) became worse and worse.
