How to Politely Tell Your Wife to Bugger Off

In just 30 seconds (from 0:53 onwards), Roger Federer manages to mock women who expect their husbands to be involved with their pregnancies ("Oh I'm pregant...I can't move around...Help me"), condescend to his wife ("Mirka is a wonderful person anyway") and only see your wives pregnancy in terms of how it benefits you ("Mirka is feeling great which is really helping me"). Coming from, say, Shane Warne, it would sound horribly sexist. But Federer just seems all the more endearing.
