Had to join in... obviously loads of variants from over the years. Here is my late Nan's

In China lived a very great man
His name was Chicker-acker-chee-chiy-cho
His legs were long and his feet were small
This Chinaman couldn't walk at all

Chorus
Chicker-acker-chee-chiy-cho-chicker-lorum
Condor-lorum, Mana-Pata-Whack
Hoko-Tow-Ko, Itchy, Kitchy, Catchy, Ko
Itchy-By, Itchy-By, Chee-Chiy-Cho

His servants used to carry him about
And on the mountains they would shout
Here he comes and there he goes
This Chinaman with the turned up toes

Chorus
(We used to shout the word Whack at the end of the second line of the chorus)
