I can add one along the lines of Carol's post.
Back in the early '90s, I skipped work midday and went to an antique store/mall in Solana Beach (north San Diego). I was the only one in the store for about a half-hour, so the store clerk was chatting me up.
Another person came in so he went to wait on her and came running back to say it was Janet Jackson. She was there with her decorator, and she was pointing and buying.
At one point, I was looking in a case and Miss J tried to finagle her way to look, too, so I body-blocked the case. (Hey, when it comes to shopping, get outta my way). :-)
Janet bought so much they had it delivered. And, after the Super Bowl, I think she can be listed as infamous.
