Late in the show, a caller asked Robin if she'd ever pleasured a man with her breasts, but Robin denied it: "No. Why would I lie? No."
Howard was surprised: "Not even as just a little fun thing?"
Robin shook her head: "It's never come up."
Howard said he'd attempt the act before any other: "Boy you're with some gentleman. I think it's the first thing I'd do to you. Even before I kiss you."
Robin couldn't imagine it: "Sitting here right now, I don't think I'd like that." Howard admitted he was joking--the act confuses him: "I don't understand guys doing that. I think it's a humiliation thing--they want to humiliate the woman. You know what I'm saying? I mean, what is that? What feels so good about that?"
Robin agreed: "It doesn't sound loving. What am I supposed to do while you're [doing that]? It doesn't sound like a lot of fun for me."
Howard then imagined the only conditions under which he'd hump boobs: "That might be something I'd think about doing if intercourse was off the table. And blowjobs were off the table. And handjobs were off the table. Yeah. And the only thing that's on the table is me rubbing my penis between your breasts."
