Almost anything by the Archpoet will fit to Gaudete:

Meum est propositum in taberna mori,
ut sint vina proxima morientis ori.
tunc cantabunt letius angelorum chori:
"Sit Deus propitius huic potatori"

My free* translation, different metre:

My only ambition's to die in a pub,
Surrounded by women and liquor and grub.
You'll hear all the angels, "Saint Peter," they'll shout,
"Come and open the gates for this drunken old lout!"

Or try this:

Meum pectus sauciat puellarum decor,
Et quas tactu nequeo, Saltem corde mechor
