Late Show with David Letterman

Show #1040 (5x178)

:

During Mailbag, various staffers show the audience their baby pictures; Dave introduces a musical comedy troupe called "The Beltway Bunch" (a rip-off of The Capital Steps), and Tony runs them offstage; just before introducing tonight's "Stupid Pet Tricks," Dave thanks Merrill Markoe (who underwent surgery earlier in the day) for giving him the idea to do this segment.
