Wikipedia has the following entry:

"A mnemonic for the fates of Henry's wives is "divorced, beheaded, died, divorced, beheaded, survived". An alternative version is "King Henry the Eighth, to six wives he was wedded: One died, one survived, two divorced, two beheaded". (Or, more succinctly, "Two beheaded, one died, two divorced, one survived.")"

I doubt this is what Shawna was after, though..
