...i am john your son !

But honestly this is sentence from a movie i searching for.

Its something about a young man named John, who search for i don't know what and don't know any synopsis of movie

But seriously all i remember is that young man, and that he at some latter point find his father i suppose who from time to time say... Whooo are you ? And John respond... I am John your son ! By this i know his name was John 😋
And there was a old car.. a Cadillac i think but i am not so sure.
Movie is from 90s or maybe latter 80s. Its comedy.
In my mind is some title Golden Balls or it was something else that was golden🤣🤣🤣 ... i am not sure.

That is all i can remember. If i get sth else on my mind i will say.
