It has the same impact on me as any other tourist attraction, but it is a cut above simulated events for kids at, say, Disneyworld.
Late in 1999 someone from National Lampoon joked that the UK was going to be acquired by Disney and the whole place converted to the United Magic Kingdom. The accompanying graphic showed the Queen and one of her guards with his head replaced by Mickey. :^)
It's interesting to me for totally genealogical reasons. All I can say is that I'm glad Charles and what's-her-face never had kids between them. I shudder to think! I mean, I'd rather not be related to her...
