Will Ferrell spoke with MTV about the huge hit "Ni**as In Paris" which samples Ferrell in the movie "Blades of Glory". You're probably all aware how the song starts off, with Ferrell's line "We're gonna skate to one song and one song only", and then mid-song he's sampled again with, "No one knows what it means, but it's provocative...it gets the people going!"  Here's what Ferrell had to say on it:

"Kanye reached out to me and I said, ‘Of course’ I was completely flattered when they asked if they could sample me into the song … and when I heard it for the first time, I just started to laugh because it felt so surreal. But I really did like the song.

We were trying to film a piece that they would use on the video boards of their concert, but haven’t gotten it together — and the whole process has opened his eyes to an entirely new career opportunity: Being the go-to sample guy on the hip hop circuit. I think [something from] ‘Step Brothers’ would be good [to use in a song]. Or the Woody Allen movie I did, ‘Melinda and Melinda.’"
