So you make a shitty attempt at a joke that's neither witty nor funny - then call us idiots. You're a winner.

Here, maybe this will help you in your future endeavors.

Lol I'm perfectly capable of laughing at myself thank you, but your joke was terrible, almost as bad your attempt at insulting me right now. That post got like 500 downvotes too so clearly nobody else thought it was funny, but I'm a nice guy so I did you a favor and found you a book to help with your problem. Hope you figure your clearly major psychological issues out, or at the very least, get better at insulting people cause you suck pretty bad. Peace.
