What’s wrong with someone laughing at their own jokes?

It's like hearting my own responses. If I didn't, no one would.

Nothing. It makes it funnier.

Absolutely nothing.

Nothing

Nothing, although it can ruin it. I sometimes can't finish a joke because I'm laughing too much. Then I realize the other person is laughing at my laughing more than they are at the actual joke.

Nothing, as long as others are ALSO laughing.

Nothing, really. It’s just when [b]only[/b] they laugh that the joke may not have worked. 😏

I always do such a bad habit lol
