Getting Even With Dad is a 1994 American comedy film starring Macaulay Culkin and Ted Danson.

The police are suspicious of Ray, so Detective Theresa Walsh Glenne Headly is assigned to go undercover and surveil him. By chance, Ray and Timmy get talking to Theresa, unaware of who she really is, and invite her for a coffee and then to dinner. Theresa and Ray get closer and they kiss. Timmy and Ray have also gotten closer, and Timmy decides that he wants to stay with his dad permanently. He urges Ray to forget about the stolen coins, because he will probably be caught and sent back to prison. Ray refuses, so Timmy prepares to return home, but at the last moment Ray has a change of heart and chooses Timmy. Bobby then appears at the bus station, and at gunpoint forces Ray to open the locker containing the coins. Ray and Bobby are set upon by the waiting police and arrested. Ray is crushed to discover that Theresa is a cop. However, it turns out that the bag in the locker was full of pennies, so Ray is released again. At Timmys prompting, Theresa finds the rare coins in a gym bag in a department store held by a mannequin, while father and son prepare for a new life together.Macaulay Culkins character was supposed to have a short haircut in this movie, but Culkin, who had let his hair grow at the time, liked his looks and did not want to cut it. His father, Kit Culkin, demanded on behalf of his son that he be allowed to keep his hair the way it was, pointing out that his character was more a rough around the edges, working class boy and not a cleancut, prep school one. He got to keep his long hair. ........
