What does Dally say to the redhead when she tells him to leave her alone?

From the text:

"You'd better leave us alone," the redhead said in a biting voice, "or I'll call the cops."

"Oh, my, my"--- Dally looked bored--- "you've got me scared to death. You ought to see my record sometime, baby." He grinned slyly. "Guess what I've been in for?"
