I really like the Peter Green translation of Catullus' #5.

5.
Gaius Valerius Catullus
trans. by Peter Green

Let's live, Lesbia mine, and love - and as for
scandal, all the gossip, old men's strictures,
value the lot at no more than a farthing!
Suns can rise and set ad infinitum -
for us, though, once our brief life's quenched, there's only
one unending night that's left to sleep through.
Give me a thousand kisses, then a hundred,
then a thousand more, a second hundred,
then yet another thousand then a hundred-
then when we've notched up all these many thousands,
shuffle the figures, lose count of the total,
so no maleficent enemy can hex us
knowing the final sum of all our kisses.


Vivamus, mea Lesbia, atque amemus,
rumoresque senum severiorum
omnes unius aestimemus assis!
soles occidere et redire possunt:
nobis cum semel occidit brevis lux
nox est perpetua una dormienda.
da mi basia mille, deinde centum,
dein mille altera, dein secunda centum,
deinde usque altera mille, deinde centum.
dein, cum milia multa fecerimus,
conturbabimus illa, ne sciamus.
aut ne quis malus invidere possit,
cum tantum sciat esse basiorum.
