London: Actor Robin Williams has revealed that he hates ferrets because they are the 'most annoying' creatures.

The 60-year-old, who gave voices to two characters in animated movie 'Happy Feet Two',  acknowledges that some people view the creatures as 'loveable weasels' but he is not a fan of them.

“The ferret is the most annoying animal. I'm probably going to get hate mail from angry ferret owners now, 'How dare you insult the ferret! It's basically a loveable weasel,” a website quoted Williams as saying.

“There's a show in America where all these people compete with ferrets and they don't even do anything. They basically hold them up and if they don't bite you might win,” he added.
