I saw this movie yesterday and I laughed all the way through it and also I liked the relationship between the two main characters (Ted and Mary). The movie sells the message that there is a difference between love and obsession and also it shows that it is good to know somebody before dating them. I give this movie an "ON" rating for it's good message and also must stress the fact that this is a romantic comedy for persons age 15 and older because of it's moderate sexual humor and strong language that consists of 40 uses of "f**k", 27 uses of "s**t", 9 uses of slang for a penis such as "d**k", "c**k", and "p***k", 17 uses of "hell", 10 uses of "ass", 5 uses of "D**n", 4 uses of "son of a b**ch", 2 uses of "crap", 5 times God's name was used as a curse, 5 times Jesus's name was used as a curse, 2 uses of "Oh, God", 2 uses of "Christ", 1 use of "goddamn", 1 use of "Oh, Christ", 1 use of "Oh, Jesus", 1 use of "for God's sake", and 1 use of "Jesus Christ". That information came form *IMDb*.
