Will Ferrell is bringing back one of his most famous impersonations on Saturday Night Live tomorrow for one 90-minute HBO special called “You’re Welcome America: A Final Night With George W. Bush“.

The HBO special will be a version of Ferrell’s limited Broadway act by the same name which ends its run on Sunday, March 15, 2009. I’ll just be lazy for a second and let HBO describe the show:

In the special, Ferrell will inhabit one of his favorite political characters from Saturday Night Live, President George W. Bush, assuming the guises of several “Ws” through the years, including the “cowboy” Bush, the “flight suit” Bush, and the (plain old) “suit” Bush. Along the way, Ferrell-as-Bush provides insights into the Bush’s childhood, his time at Yale, his stint as a major-league baseball co-owner, his emergence as a political figure, and his cherished if checkered tenure in and (frequently) out of the White House.

Sounds good! I actually saw the commercial for it last week while watching TV but totally forgot about it until just now when I saw another commercial for it. Anyway, the show airs tomorrow, March 14, 2009, at 9PM EST on HBO. Tune in for a good time!
