Every great sitcom features a wildcard character, the unpredictable scene-stealer who elevates every moment they're in. From Kramer's antics in Seinfeld to Urkel's charm in Family Matters, to Charlie's craziness in It's Always Sunny, these larger-than-life personalities inject comedic energy that captivates audiences.

However, few have perfected this archetype like the legendary Janitor from Scrubs. Whether the episode was heartfelt, hilarious, or utterly unhinged, The Janitor was always lurking somewhere in the halls of Sacred Heart, ready to derail JD's day with another unforgettable prank or bizarre conspiracy.

But how did this iconic character come to be? Would Scrubs have been the same without him? And the question fans have debated for years: did JD actually stick that penny in the door?

Only The Janitor knows for sure.
