Aldrin Justice is Lily Aldrin's personal technique of punishing people. The basic premise of it is when someone "misbehaves" around Lily, she punishes them by "taking one of their toys away" (i.e. something of value to them). This annoys the gang a lot and they continuously tell her to return the stolen items. It was originally used to punish students in her kindergarten class but this doesn't stop her using it on adults as well. She normally returns the items by the end of the episode.
