What's an orphan's favorite part in the Wizard of Oz?
When Dorothy says, "There's no place like home."
Orphan's Favorite Wizard of Oz Part
Explanation
The joke plays on the irony of an orphan, who doesn't have a home, liking the part in "The Wizard of Oz" where Dorothy says "There's no place like home." It's a bit dark because it highlights the absence of home for orphans and uses that to create the humor.
