'How I Met Your Mother' cast appears on David Letterman to read series finale Top 10 List

The series finale of How I Met Your Mother airs on Monday, March 31 on CBS, and the cast has begun doing the rounds to promote the final episode of the beloved sitcom. One stop on that tour was The Late Show with David Letterman on Tuesday night, as the main five players stopped by to read one of Letterman's famous Top 10 Lists.

Josh Radnor, Cobie Smulders, Neil Patrick Harris, Jason Segel and Alyson Hannigan stood side by side and read off a list of Top 10 Surprises in the Final Episode of "How I Met Your Mother." Of course, none of these were real (we hope):

10. Finale? We've been cancelled?! (Jason Segel)

9. The real father: Frank Sinatra (Cobie Smulders)

8. Fairy tale wedding with the cast of "Blue Bloods." (Josh Radnor)

7. You know that bar we hang out in? We buy it and turn it into a Duane Reade. (Alyson Hannigan)
