Why was cinderella such a bad basketball player?

This is a funny joke! It plays on the idea of Cinderella being a "glass slipper" and a basketball player needing strong shoes. Here's why it's funny:

* Wordplay: The joke uses the phrase "glass slipper" literally, even though it's from a fairy tale.

* Unexpected Twist: We don't expect Cinderella to be a basketball player, so the idea is humorous.

* Visual Humor: We can imagine Cinderella trying to play basketball in glass slippers and failing miserably.
