Titles of romances are getting goofy! What do you think of....

Duchess, Countess, Butler, Duke which is sort of a take off of Tinker, Tailor, Soldier, Spy?

Or should that read (because the hero is a duke): Grandma, Auntie, the Duke and I???

Or since my hero, the duke, looked differently than he does now when young, could the title be: The Frog and I?

Yes, I am writing romcoms these days for shorter works. And the title should fit, yes?

Tell me what you think of these!
