Lady "KaKa"

You know, most people should have at least heard about Lady GaGa. Recently, I have been hearing some songs by her, and my brother usually stands by me as I rock my head off. Since he kind of likes the songs by Lady GaGa, I decided to teach him to say the word Lady GaGa. Suprisingly, I did not mention anything to him, but he started to say those words. As you might not know, my brother calls me "KaKa". So once her starts to say "Lady GaGa", it always ends up as "Lady KaKa". My helpers and I laugh at that. Don't you think it's a funny joke?
