We got to see Ashton Kutcher in Two and a Half Men mode last night for the first time, as he and his costars Angus T. Jones and Jon Cryer read off the top 10 list for The Late Show With David Letterman. Broadcasting live via satellite from the set, the guys presented "The Top 10 Reasons to Watch the New Season of Two and a Half Men." Though the intro is a little awkward, most of the list is cute — it includes references to Ashton's Dude, Where's My Car? as well as fellow CBS sitcom How I Met Your Mother. Check it out, and tell us if you're planning on tuning in when Ashton makes his debut!
