An Anthem for Fireworks

To the tune of "The Star-Spangled Banner"

Oh, say, can you see, by the dawn's early light,
Sues so proudly impaled at the twilight's last gleaming?
Whose hair-stripes and eye-stars, through the perilous fight,
O'er the plotholes we watched were so luridly streaming!
And the agents down there, curses bursting in air,
Gave proof through the night that HQ was still there!
Oh, say, does that blood-spattered halberd yet wave
O'er the urple and the twee, and the writing depraved?
