This doesn't get old.
Jimmy Fallon has had the world in stitches with his mash-up videos of US newsreader Brian Williams rapping to 'Rappers Delight' and Snoop Dogg's 'Gin and Juice' - and it doesn't stop there.
When Williams appeared on Fallon's 'The Tonight Show', he joked that he wanted some control over future videos.
"You've done this to me now seven times," Williams told Fallon. "I would like some pride of authorship ... Any Luda would be great. I'll do 'Rollout.'"
Porthouse Media, a company that saw Williams' request, accepted the challenge, creating a brlliant mash-up video of Williams rapping to Luda's 'Rollout.'
