Stars making fun of their image on late night talk shows is nothing new, but there's something special about watching a macho tough guy like Bruce Willis skewer himself for night owl television audiences. On last night's Late Show with David Letterman, Willis claimed to have a clip from the recently wrapped fifth 'Die Hard' film (titled 'A Good Day to Die Hard'), but it was really...well, just scroll on down and see for yourself.

Yep, that's Bruce Willis as John McClane making 'Twilight' jokes. Between this and his incredibly silly cameo in the ridiculous 'The Expendables 2,' Willis has definitely reached the point in his career where looking cool has become a low priority (there was also his comedic turn as a bumbling cop in the wonderful 'Moonrise Kingdom'). However, fans of Badass Bruce Willis, who cringed through the clip above, can take solace in knowing that he'll be back to killing bad guys with machine guns and steely glares in 'Looper' on September 28.

'A Good Day to Die Hard' won't hit screens until 2013, but 'Twi-Hard: With a Vengeance' has already hit screens in our hearts. Or our nightmares. We're not sure yet.
