My Headband lyrics

[Rachel]
There you rest, with all the rest
Of my accessories on my nightstand
You're red or yellow
And like a good fellow
Sometimes you get lost in my mess
[Rachel]
But when schoolgirl pigtails won't do
And I need to control my 'do
You're the only one I can count on
My headband
You're my headband!
Wrapped right around my melon
You're a product like Magellan-
[Finn]
Hold on. hold on. Uh, is this a song about your headband?
