A goofy chick is much like comedy itself. It all depends on timing.
Woman with a good sense of humor can brighten your days and liven your nights, but do you really want to be with somebody who makes fart sounds at your grandmother's eulogy? Someone who spends the rent money on a dinosaur pancake mold so that you no longer depressed about the rent? Someone who's going to crack jokes at a BLM meeting?
On top of that, a lot of funny people tend to have very tragic lives. Look at all the professional comedians who fell victims to drugs, alcohol, and suicide.
Worst of all, if you stay with her long enough those jokes aren't going to be funny anymore. You've seen and heard them all before. Once she's figured that out it's on to the next.
