Burmese Joke

A classmate from Burma named U Tin (because he is critical of his government so we can't say full name) has a lot of jokes which surprises me at first because I thought the seriousness of his place would translate to his being serious (like the Cambodians in my class) in demeanor. But you can't take that away like you can't take the humor from the Pinoys during the Marcos times. So anyway here his joke:

One time, a boy climbed a tamarind tree to get leaves and fruits for soup when a couple came and rested. The boy watched until:

He do she
She do he
I do me
I fall tree
