Anything I Put My Mind To

Okay, Qbdkylee, you need to listen up because you are not the sharpest tool in the shed. You see, the joke works because you are saying that you are thinking about killing yourself, and then immediately after that you mention that your mom said you can do whatever you want. The funny part is that you could kill yourself, because that's something you set your mind to. This is called dark humor, and it's funny because it is kinda tragic.
