What does your family cat do that's unusual for cats and very funny?

Our family cat fetches rope and strings on command. You can throw the rope down the stairs and say "go get the rope" or "string", and she will go and get it and bring it back to you for you to play with it with her. She goes crazy over rope and string! The only downfall is, she wants to play with the rope or string for hours! She'll just keep going to get it and bringing it back to you even when you don't tell her to sometimes lol. And she'll meow-whine like she's saying, here, play with me now lol! Maybe I should put her on one of those shows and make some money with her act lol. This is odd because fetching is usually a dog thing, not a prissy cat thing lol.
