David Letterman got paid a visit by the cast of How I Met Your Mother who were invited to read the Late Show's Top Ten list!
Jason Segel, Neil Patrick Harris, Alyson Hannigan, Cobie Smulders, and Josh Radnor all took turns listing off the surprises in the final episode of How I Met Your Mother!
We're not sure if these tears running down our face are from laughter, or from the sheer devastation that is contemplating a world without HIMYM, especially since we are marching towards their final episode, which will air March 31st.
Ch-ch-check out the HIGHlarious list that is one of our top ten Top Tens (above)!!!
