Shower thoughts

But if a siamese twin with a normal body and two heads have a child with someone, whose child is it then?

But really though how many things are there...

Tarzan looked pretty hairless aside from the dreads. Then again, it seems drawing body hair isn't the done thing in animation. Gaston had chest hair but I can't think of any others...

When several women live together their periods usually sync so I guess they would be at the same time

Identical twin guys. Are their penises the same size?

Mermaids would lay eggs and the male would fertilize them.

What if a mermaid gets legs and walks on land, becomes pregnant, and then becomes a mermaid again?
