Luke Dunphy is Claire and Phil's 11 year old rambunctious son, who is often doing his own thing. At times, he can be a trouble maker, once shooting his sister with a toy gun and getting into a fight with Manny at school. Luke is very innocent and does not always understand the repercussions of his actions, like most children; he once announced at a family gathering that his mom said that his grandfather's new wife was a "gold digger". Both parents agree that they "dropped the ball" with regards to raising Luke; Phil once tells Claire that he considers Luke to be their dumbest child (though, based on the way he conceded to Claire's assertion that Haley was their dumbest child, this was most likely an attempt by Phil to hedge the wager he was making with his wife at the time). When studied by a psychologist, she said his type of behavior was normal for someone with above-average intelligence; afterwards, Phil and Claire accidentally left a wandering Luke behind when they left the office, but they ended up being impressed by how calmly he made his way back home (in a limo!) and decided he would do just fine in life
