Problem Child 1990.
A child is passed around due to his behavoiur and turned over to a orphanage run by nuns. He is soon adopted by a caring man and his obnoxious wife. He leaves a wake if destruction behind him and his only friend is career criminal the bow tie killer.
Early slap stick comedy from the 90s, John Ritter plays the doting father who thinks he has adopted Satan, dressings child as the devil for a party is a great choice. Amy Yasbeck stars as the annoying wife Flo. Right from the start it has it's laughs with the voice over from Michael Oliver (Junior). I'm sure we were young a well behaved all the time
. Still worth the watch and laughs.
