I know the Little Pigs isn't specifically for counting-out, but it reminds me of one I learned whilst young:

Ocka-Bocka Stona Crocka,
Ocka-Bocka Boo.
Ocka-Bocka Stona Crocka,
Out goes you!

And a German one:

Eine kleine dichmadam
Die stieg auf die Eisenbahn.
Eisenbah sie crackte,
Dichmadam sie lachte,
Aus bis du!

(A little fat woman climbed on the street-car;
the streetcar cracked, the fat woman laughed.
Out with you!)

Anyone have others? And are there any counting-out games involving pigs?
