Problems with flash sites

An interesting one came through my inbox today.

A site made entirely of flash, with more or less just the embed/object tags on the page was showing as a different site in Google search results.
The reason is that both sites only had the text "This site requires needs flash" as the only indexable content. No other meta data to set them apart, and both referenced a flash file of the same name.
Google assumed they were the same site and stopped serving one, since there wasn't any text to extract from the flash file itself.

Please take note - if you must use Flash, at least include a unique <title> tag.
