B'cause skewetons don't wear clothes.

Sean is such a little nudist. He LOVES to be naked. He gets dressed every morning, and yet most days, he ends up naked at some point. 

Conversation that just happened:

Me: "Sean! Why in the world are you NAKED?!"
Sean: "I'm a skeweton. They don't have clotheses."
Me: "Sean, it's winter. Skeletons wear clothes in the winter."
Sean: "Mama! (exasperated) Skewetons don't get cold, b'cause they don't have any meat. They JUST HAVE BONES."

What on earth should I reply to that?

Here are a few pictures I took of the boys the other day:
