The cake sounds excellent--I'm sort of reminded of the Central Asian custom of sheep's head as a festive dish as well, but the John the Baptist and Salomé reference is much more amusing.

The person to whom it was served took pictures, but unfortunately I do not have his e-mail address.

a movie about people in WWII-style piston-engine fighter planes fighting each other with battleaxes (don't ask me how it worked--it didn't make sense at the time, let alone after waking)

Are you kidding? I'd be disappointed if it didn't happen in a webcomic somewhere.
