Miss Stephen's Divorce

Listen up, buttercup! This joke is a play on words, see? It's kinda like when you tried to build that birdhouse, and it ended up looking like a squirrel condo. "Float" can mean both "to drift on water" and "to be socially successful". Miss Stephen couldn't keep her marriage afloat, get it? You're about as sharp as a marble, but hopefully, you get it now.
