That Hugh Jackman, what a sport! If you had a talk show and he was a guest, I have a feeling you could be like, "So, for this segment, I'm gonna dress as a Christmas cat and you're gonna take me from behind in front of a live studio audience whilst singing the State Farm jingle." And he'd be like, "OK, just let me get my Santa hat!" Ya know? He's just so accommodating.
Anyway, this is incredibly delightful, and I hope we're all lucky enough to sing a duet with Jackman at some point in our lives. I think it could happen if we wish hard enough. Christmas miracles abound!
