About[]
Janitor's Squirrel army. ("My First Kill")
Seen only a couple of times over the nine seasons of Scrubs, Janitor's apartment is known to have a shower with a window right by it, which J.D. looks through to see the Janitor naked. ("My Interpretation")
Janitor's house also has a garage (or workroom) where Janitor practices taxidermy, such as building his squirrel army. ("My First Kill")
