VIDEO: USMNT captain Clint Dempsey appeared on "Late Show with David Letterman" | SIDELINE

Seattle Sounders and US national team forward Clint Dempsey was the featured guest Wednesday night on the Late Show with David Letterman and reminded us once again just how cool a kid from Nacogdoches, Texas, can be. 

Answering "yes, sir" and "no, sir," to Letterman's every question, the USMNT captain oozed class and respect — characteristics not always displayed by many, even those significantly below his current celebrity status. He was someone of whom soccer fans could be proud on America's most popular late-night talk show.

Dempsey fielded the typical "why is this, why is that" soccer questions from Letterman and probably taught the 67-year-old more soccer during the 12 minutes in which he was on stage than he's known his entire life.

Dempsey also used the Late Show setup to give a shoutout to a special someone in his life: his baby mama.

What baby mama (Dempsey's wife, for the record) doesn't want a birthday shoutout on Letterman?
