Will Ferrell interviews Roger Federer at the Australian Open on Monday as John McEnroe looks on.

Roger Federer winning his first-round match at the Australian Open wasn't a surprise, since the Swiss great hasn't lost his opener at a grand slam in 15 years.

What was a surprise was just who he chatted to afterward on the court .

Post-match interviews are commonplace on the big show courts at Melbourne Park -- but nobody expected actor and comedian Will Ferrell to be the one posing the questions to the defending champion.

Tennis fan Ferrell is a US Open regular and attended Day One Monday in Melbourne.

Taking on the character of Ron Burgundy from his "Anchorman" films, the actor stole the show from interviewer and tennis great John McEnroe -- as a somewhat nervous Federer looked on.

It was by far the trickiest part of the 19-time grand slam champion's day after an easy win against Slovenian Aljaz Bedene.

Ferrell asked Federer such posers as whether he felt like a silky gazelle on court, whether he was a witch or a vampire, and whether his secret was eating wombat meat. Federer could only block back Ferrell's comedic aces.

The actor signed off with his famous catchphrase from "Anchorman": "Stay classy," inserting Melbourne at the end instead of San Diego.
