My kids were chosen to be in MGM's Christmas parade one year and it was definitely random. As we entered the park that day a CM with a clipboard in her hands walked up to us and I thought to myself "Oh no, she wants us to stand here and do a survey" and I almost smiled and walked on by but she snagged us and asked if we'd like our kids to be in the parade. "Sure" we said. Then, after telling us the parade would start in about 20 min, she took our kids and disappeared through the gate of the large wood fence near the park entrance. My husband and I stood there and waited -- as it occurred to us we had just let our children leave with a total stranger. But soon they emerged as part of the parade -- dressed as Christmas tree ornaments along with about 8 or 10 other kids. Great magical moment!
