"You wish!" Jack replied with a laugh. "You couldn't have had her even if you were the last man on Earth!"
Jack finished his remaining shot, tilted his head a bit to the side, and shot John an 'oh really?' look.
"I could care less if you're jealous. And you're the one who always has to be the center of attention. You just can't stand not getting your way, can you?"
Placing one boot on the foot rest of John's stool, Jack leaned in close and said firmly, "I'm taken."
Then he promptly shoved John's stool backwards, away from him.
