Louisiana library card

When your parents are in the next room so you and your sister go to pound town quietly

Brother: looks like we might have to pull the ole' Louisiana library card today, mom and dad are home *insert a subtle "Yee yee"*

Sister: mom and dad died in the crash 8 years ago brother...you gotta let it go..
