Ah, but in the original song, it was the wife. And Kotetsu is in her place. It's very easy to draw the conclusion that he's the wife in this relationship.
I love this vid. It's so funny and it fits so well. But then I think to my self, what was the original title? And then I realize the possibly unintentional implication the Tiger's an uke. That doesn't stop being funny, ever.
