Was truly as chaste as a nun
Despite some men's urging
This queen stayed a virgin
Majestic, but not really fun.
Couldn't come up with much for the prompt weak. Then the Elizabeth I speech in Tilbury on the eve of the Spanish Armada. You know it - it was where she said "I may have the body of a weak and feeble woman, but the hear and stomach of a concrete elephant" - come to think of it, that may well have been Blackadder.
