Brought Home the Wrong Kid
A rather common plot in sitcoms is for a babysitter or neglectful parent to take the child (or more as sometimes happens) out to the park or somewhere for the day, usually a place where there will be plenty of other children around. Through Finagle's Law
or the laws of sitcom universes, the parent will accidentally bring the wrong child home only realising this when it's too late. The rest of the episode will either have the minder trying to find the original baby or else just trying to conceal it from the parents. For obvious reasons this only happens with babies and extremely young toddlers. While it is common for the neglectful babysitter to be either male or female, if it is an actual parent bringing the wrong baby home it is always the father. Do not confuse with Switched at Birth
