Be on the look-out, folks, the roads of Los Angeles just got a little more bizarre. There I was, driving near my office in Beverly Hills yesterday, when a quick glimpse in the rear view mirror confirmed my worst suspicions. I was being followed by a full-service McDonald's on wheels. "Just what I need," I said, as the Golden Arches drew closer, "I'm being tailgated by Ronald McDonald." I pulled over on Hillcrest to let the restaurant pass, but -- to my surprise -- it pulled over, too. Curiosity got the better of me and I got out of my car. "I'll have a Big Mac and and order of Fries to Go," I said to the woman who seemed to be in charge. "You're back!," she said, "You're Mr. Annenberg, right?" Her brain was obviously more scrambled than an Egg McMuffin. I'd never seen her before in my life ... and how strange that she seemed to be confusing me with Neighbor Charlie. "I don't know what you're talking about," I said. She went on. "Are you trying to tell me that I didn't just see you two hours ago at the Post Office?" I looked around, half-expecting Rod Serling to appear. "Cancel my order," I said, "I'll just grab something from the Drive Thru, instead." I later learned that the McDonald's-on-Wheels was in town for a video shoot.
