Help me identify this sound clip/song?

I was at a friends yesterday and I heard this mp3 over the course of the evening that I swear I’ve heard somewhere before, but I cannot place it.

It’s a man speaking… and somewhere during his monologue, another voice (possibly also his) breaks into song… and the first voice says “Shut up! Shut the hell up!” or something similar.

I know that’s not much to go on, but holy cow. This has been plaguing me all morning and my friend has no idea what track I’m talking about.

If it helps, the voice almost sounds like Dane Cook, but it didn’t seem light hearted or funny at all.

I’m not sure what song is, but I suspect the exchange you heard was sampled from the movie “Bulletproof”. Why do I know that? No clue.

Is this it?
