It's all in the name

INDIAN SETTLEMENT. TEPEES ETC.

VERY YOUNG BOY: Tell me, Bald Eagle, where de we get our names from?

BALD EAGLE: Ahh, that's a VERY good question. I will tell you how the wonderful
tradition of naming works. When a baby is due for birthing the mother squaw goes
into the maternity tepee. The father goes with her. When the child is birthed the
father leaves the tepee and the child is named after the fist thing that the
father sees. Tell me Two Dogs F**king, why do you ask me this?

This feels familiar to me.

I thought it was SOOO old I'd get away with it!

NAUGHTY

Aye a very old and well worn joke told almost verbatim. - maybe you could have changed it to 'dog having a shit' which for some childish reason makes me laugh.
