Possible alternate titles for the historical romance novel Wicked as Sin, which seems a bit wan for a saucy bare-chested aristocrat:

Wicked As a Bag of Hammers
Wicked As All Get Out
Toot! Toot! All Aboard the Wicked Train!
If You Looked Up Wicked in the Newly Invented Dictionary, There He’d Be
Wicked by Appointment to the Queen (Purveyors of Fine Wicked Since 1689)
10 Pounds of Wicked in a 5 pound bag
Wicked like Wombats
