Ashton Kutcher appeared on The Late Show with David Letterman last night to promote his new film What Happens in Vegas - but didn’t do much promotion in favour of just chatting about his marriage to Demi Moore and the dumb things you can do in the winter in Iowa.

As with his webbed-toe thing the other week, he comes across as a genuinely nice and funny guy on these things - and I love his shirt/jumper combo here too. Purrr.
