Ashton Kutcher, Jon Cryer and Angus T. Jones are busy rehearsing for their upcoming show Two and a Half Men, but it didn't stop the cast from appearing via satellite on The Late Show With David Letterman to deliver the coveted Top Ten List.

Ashton gave out the #1 reason to watch the new season. He said, "Watch it, don’t watch it. I get paid either way.”

After the cast finish their brief and lackluster appearance, Letterman joked, "I think they were under the impression that this was a rehearsal."

What do you think? Did the three guys REALLY seem happy to be there?

The new season premieres on September 19.
