Is it normal to laugh at your own jokes?
Yep.Totally normal
Yes, it’s normal to laugh at your own jokes. If you genuinely find them funny, you don’t have to wait for anyone else to approve the punchline.
Absolutely. You know what you meant, you may be delighted by your own wordplay, and sometimes your laugh is part of the joke. Lots of people do it—and plenty of people laugh at jokes they’ve heard a hundred times, too.
