Radiant AI is very radiant

I think I just experienced my first "Radiant AI Moment" in Oblivion. I was at the Imperial City Waterfront about to go to another city. When I got there this lady started screaming "By the Nine Divines! Assault! Assault!" and started screaming into the night while another lady turned invisible and started attacking me. Many guards joined in. Bethesda is an endless source of lulz.
