Jeff Caldwell performed on Friday night's episode of Late Show with David Letterman. As Letterman said, it wasn't Caldwell's first time on the program. This time around, he provided insight on living with a younger wife, and why they're not planning on having kids anytime soon. Some topics here may seem well-covered, but Caldwell seems to have his own take on many of them.
