Found on a web forum I read.

[krfsm]

Winter is icumen in,
Lhude sing Goddamm,
Raineth drop and staineth slop,
And how the wind doth ramm!
Sing: Goddamm.
Skiddeth bus and sloppeth us,
Freezeth river, turneth liver,
An ague hath my ham.
Damm you; Sing: Goddamm.
Goddamm, Goddamm, 'tis why I am, Goddamm,
So 'gainst the winter's balm.
Sing goddamm, damm, sing goddamm,
Sing goddamm, sing goddamm, DAMM.

ETA It is actually a parody by Ezra Pound, apparently. Still fitting.
