Wagner's Yo-Yo's or Why I Am Not Valkyrie Material

So I'm at work today, preparing BOD samples, filling bottles, reading on, that sort of stuff. And I have one of my classical CD's in the player and it's playing Ride of the Valkyries. Wagnerian opera at perhaps its finest, or at least, its most parodied. And the Valkyrie's battle cry is "Ho-to-yo-ho!" So here I am, singing along to the famous five-note fanfare: Ho-to-yo-ho-yo, Ho-to-yo-ho-yo, Ho-to-yo-ho-yo, Ho-to-yo-ho. Except I'm paying far more attention to what I'm doing (as I should) than what I'm singing. So I keep switching syllables around. Finally, I realize that I'm singing at the top of my lungs: Ho-to-ho-yo-yo, etc. Clearly, I am not Valkyrie material.
