It's the mother in laws birthday and she wants a film but does not know what it is called which is a great help !!!! So I am on a mission to solve the problem. It starts off with a man who looks like Dan Acroyd apparantly, he goes home one day and sees his wife in bed with his boss, but it turns out to be the wifes twin sister. He goes on a rampage and some black guy holds him up for his wallet, he refuses but at some stage he teams up with this black guy and plans to rob the boss. Another clue is apparantly someone ends up stood in petrol with his feet on fire !!!! It is a comedy film from about 15 20 years ago. Anyway I early need some help as it's going to be part of the mother in laws bithday present. Now it would not suprise me if these clues are from different films a she is a bit scatty at the best of times but I have to try. Any ideas.
