Louis C.K. has stated that when he was a teenager, he really stole his junior high school's scales and sold them to a drug dealer for marijuana but never got caught.
Dedicated to Philip Seymour Hoffman who was supposed to have a role in the episode but sadly passed before filming.
The apartment number of the drug dealer that Louie brings the scales to is "2B", a few episodes earlier we see that Amia and her aunt have the same apartment number.
After the dealer tells young Louis to get out, there is a man visible outside the dealer's door.
