The War at Home - Season 1 Episode 8 -

When Dave thinks the kids are getting away with too much, he implements a zero-tolerance, pro-spanking policy, since talking to them just isn't working. However, they all think he's bluffing and don't take him seriously. After Larry becomes the first to be spanked, he moves in with his friend, Kenny. Now, Child Protective Services is called and Dave will have to answer to them.
