Irina Shayk appeared on David Letterman last month to promote her Sports Illustrated swimsuit cover, and I just stumbled across the very funny interview. Forgive me if I’m surprised by a smart model. I’d also like to point out that I’ve noticed something awry with David Letterman after I’ve religiously watched his interviews. Though I might be wrong about this, I’m under the impression that he doesn’t think women are funny. Every time Irina makes a joke, Letterman moves onto the next question, and refused to verbally spar on any level. In fact, there are moments where I think he’s actually making fun of her. Watch the interview below and judge for yourself.
