Faith was having a pitched fight in an alleyway with a towering brown shaggy-furred demon when a taxi cab burst into the narrow space, knocking the creature completely off its feet.
She was able to finish off the demon smoothly enough and turned to thank her rescuer, only to realize with a start that he was a three-foot-tall duck.
“So, I take it you’re new to Cleveland,” he said, stepping back to hold open the door to his cab. “Mind if I show you a few sights?”
“You move fast, for a duck,” she said, taking him up on his offer.
“The name’s Howard and if you want to talk about fast, you should see me in action. I know Quak Fu.”
...
After a week getting to know him and a rather odd encounter with his ex-girlfriend, Faith invited Howard up to her hotel room.
After several bouts of... pleasant activity... Faith fell asleep, curled up next to him in a warm ball, only to be rudely awakened by him yelling into the room’s telephone.
“And that’s exactly what I think of your offer!” were his last words before he slammed into its cradle. “Sheesh! What a pervert! Room service, my ass!”
“What happened?” she asked, sitting up and wrapping the covers around her.
“I asked him for another condom," he replied, blushing beneath his feathers. "And he wanted to know if it was going on my bill!”
