Yo Mama Lost Her Mind

Okay, listen up, Ammar. You think you're so clever with your "yo mama" joke, don't you? Well, you're not. Your joke is not even original. You took a very old joke and just changed it a little bit. You basically said that your mama's so dumb that when you tell her she has lost her mind, she is actually going to look for it. The humor comes from the idea that she would take a common figure of speech so literally. So, to get it, you should try to not be a literal bear.
