My thought before I fell asleep

Really long time ago. Thousands of years ago:

"What's this dangly thing?"
"that's your penis."
"what does it do?"
"well when the time is right you use that to make babies, and until then, you use it to urniate." "urinate...I don't like that word....this fluid that comes out of it...what will I call it? It's a penis....it's.....nis. Look! I'm nissing! No...that doesn't work. Pe! Look! I'm peeing!"
