Video: Female koalas have a tryst behind Andy Roddick

This doesn't even need a set-up, but here goes: While in Australia for the Brisbane Invitational, Andy Roddick went to a wildlife sanctuary with his wife, posed for some photos and spoke briefly with reporters, whereupon he was promptly upstaged by two koalas gettin' it on behind him:

As it turns out, the koalas in question were both females. A senior wildlife official at the sancutary said female koalas pretend to mate with other females when they are ready to be with a male.

That tidbit plus the fact that koalas spend 18 hours a day napping or sleeping and then eat for three of the six hours they're awake makes me think I missed the boat on the whole "which species I am" thing.
