Episode where Will Ferrell pulls a gun on Conan?

Anyone have a link to the episode or clip where Will Ferrell pulled a pistol on Conan on the late show and I think forced him to plug a movie or something.

I remember watching the episode and you could see the pistol in a shoulder holster under Wills jacket the whole time, and thinking "WTF!", then he whipped it out and took Conan hostage.

Was an awesome bit I haven't been able to find anyplace.
