First there was "I'm Fucking Matt Damon," then "I'm Fucking Ben Affleck," and now "I'm Fucking Seth Rogen." Ha ha ha? Yay, "viral" videos by celebrities.

If you can do a Sarah Silverman impersonation, feel free to use these replacement lyrics for that song:

[Spoken into camera while noodling around on acoustic guitar] Hi, America. It's me. I'm... I'm really sorry about this whole thing. It turns out that just because big-time Hollywood movie stars are "good sports," that doesn't necessarily mean everything they do is worth releasing to the public. Not even once, let alone three times. [Looks off-camera] What's that? George Clooney just did one of these? Figures. Because you see...

["Rock" music kicks in as Jimmy Kimmel steps into frame]
I'm fucking not funny
(We're fucking not funny)
Never been and never will
I'm fucking not funny
(We're fucking not funny)
Shitting out the lamest swill

I can't write and I can't sing, I can't do a single thing
If you're laughing at this song, you're a guy who craves big dong

I'm fucking not funny
(We're so fucking not funny)
But you see me on TV
I'm fucking not funny
(We're fucking not funny)
I'm like comedy VD

[Acoustic break]
Hey world, don't take it rough
I didn't work on my craft enough
If I talk like a cute little girl and spew filth, then the cutesy-wutesy filth is even better than actual jokes

[Back to "rocking"]
I'm fucking fuck fuck fuck
(Fuck fuckuddy fuck-fuck)
Fucking fucking fucking fuck
Fuck-fuck-fuck-fuck-fuck-fuck
(Fuuuuuuuuuuuuuuuuuuuuck)
God, I really fucking suck

I got smugness by the ton, not a single ounce of fun
It's ironic, doncha think, getting paid to really stink

I'm fucking not funny
I'm fucking not funny
I'm fucking not funnyyyyyy, yeah yeah

[Silverman and Kimmel pull pump shotguns from offscreen and put the barrels under their chins at a 45-degree angle] Sorry, everybody. [Cut to black, shotgun blasts, wet splats, wild applause]
