I've dressed as a banana and waved a sign on a hot and humid Florida street corner to get people to call a number for a weight loss clinic. Humiliating... but it paid cash which paid bills. I'd dress as a banana every day if it stopped my kids from being homeless or going hungry. Hell, if I wasn't married, I'd even consider dancing again. You do what you gotta do.
If you're going to be a street performer, make sure your local municipality has not established an ordinance against them.
