Learnt from my Auntie who grew up in Bangladesh:

Once in China, there lived a great man,
His name was Chikka-rakka-chee-chy-cho,
His head was tall and his feet were small,
And this little man couldn't walk at all!

Chikka-rakka-chee-chy-cho, chikka-lawrum,
Condo-lawrum, manna-fakka-one.
Oko-poko, ichy-potchy-ichy-potchy,
Ichy-pie ichy-pie, chee-chy-cho!
