It's a Hard Knock Life

Orphaned rules are those that come to pass without proposers,

But worse they can't be placed on the board - they're also homeless.

The general connection posited by Dolphin was correct,

But specified information was absent nonetheless,

And in noting the identity of the singers had not been guessed,

Our proposer found her head repeatedly colliding with her desk.
