As the comedians note in tribute to David Letterman (from last night’s Kennedy Center Honors on CBS), it is fun to see Dave be uncomfortable. People (namely Tina Fey, Alec Baldwin, Jimmy Kimmel and Ray Romano) complimenting and honoring him definitely makes him squirm.

This tribute was great to watch, except the end, when producers made all four presenters interact in a scripted manner. That was awkward for everyone.
