VanDam was later called back to be congratulated, and Stern expressed his interest in the impression and the reaction it received.

Stern then told VanDam that he would contact him to make more appearances, as well as writing "filthy" lines that the real Letterman would not say.

VanDam recorded prank calls and other clips which were taped and assembled by show staffers Sal Governale, Richard Christy and Benjy Bronk.

VanDam starred in the Family Guy episode "Back to the Woods" on February 17, 2008, as the real Letterman.
