Will Ferrell doesn't "give a s**t" how he looks.
The 47-year-old comedian recently gatecrashed the birthday party of a 100-year-old woman at an assisted living facility in Los Angeles - where he sang alongside two elderly women - and he insists such bravado is key to his career success.
The 'Anchorman' actor explained: "I just don't give a s**t how I look.
"It's just that reckless abandon, the commitment to bare all. It's kinda like walking on hot coals.
"It's not that I wasn't afraid to take the first step. Just once I did, the coals were never that hot."
And Will concedes he's happy to take outrageous risks with his comedy, even if it's not to the liking of everybody.
He told the April comedy issue of Britain's GQ magazine: "There's a perverse pleasure in knowing that 75-80 per cent of people will get it, but knowing 20-25 per cent will not only think it's not funny, but will be like, 'That's dumb. Why would we do that? I don't get it. We hate that guy!'"
What's more, Will revealed his humour is based entirely on instinct, much like his comedy inspiration and former 'Saturday Night Live' star Steve Martin, 69.
Will said: "[He was] this anti-comedian comedian, he'd walk out with an arrow through his head... I just loved that. I read in one of his books that some people go with political comedy... but why not just go with instinct?"
