‘Roger, are you a witch or a vampire?’

Roger Federer had to answer some tough questions during his post-match interview at the Australian Open on Tuesday.

Funnyman Will Ferrell watched the defending champion’s 6-3, 6-4, 6-3 victory over Slovenian Aljaz Bedene on Rod Laver Arena.

After the match the American comedian interviewed the 19-time Grand Slam winner and naturally came up with some bizarre questions.

Federer, though, answered most of them like a pro.
