I was searching on the net to find out the real words to eenie, meenie, minie, mo etc. and i came across this site.
I am from England and all my life ive thought that it goes..
eenie, meenie, minie, mo catch a pity by it's toe if it squeals let it go. eenie, meenie, minie, mo
i asked some of my friends and the said the same rhyme replacing "pity" with 'robber' 'tigger' 'tiger' and 'fishy'. We then asked another person and they said n****r.

As for playing tag I used to only say 'your it' and that was only 7 years ago.
