Sorry folks, I am an idiot. Perils of posting to the Corner while on the phone (and while not being a football fan). This emailer’s response captures the situation. My apologies:

Jonah,
Either you’re being silly or you are truly clueless. That link is to a
Pittsburgh Steelers’ fan remake of the original muppet song. One of the
more popular Steelers’ players is named Troy Palamalu (spelling is probably
incorrect). So they made a funny song about his name and dubbed it over the
original.
My 7-year-old son is a raging Steelers fan (I’m a mild fan by
comparison…Hockey is more my thing). So I’m pretty damn sick of the
song…but it was kinda funny at first.
