This movie was funny for all the cat and mouse games going on between Richard Kiel and Ryan O'Neal, but the part I remember the most was Jack Warden. I will forever say that the funniest line in a movie I have ever heard was his line at the end of the movie. In the ending scene, Ryan O'Neal and the leading lady are riding in a gondola in Venice. In a seperate gondola, Warden and woman he has fallen for are riding. In the first boat, O'Neal and the woman are kissing, being romantic, as expected in such a romantic setting. Meanwhile in the next boat, Warden turns to his lady,and with bedroom eyes in this city of love, leans over and gently whispers to her..." How long have these streets been f**ked up?" . I roll every time I see that. ( pardon the language, but it is a quote.) That aside, it is still a relatively funny movie.
