the first compelling argument i've heard against sleeping naked:

there is a man. he is sleeping naked. his three year old daughter, having stirred from her slumber, foggily walks into his room in the middle of the night. she moves to his side of the bed. to hoist herself up, she reaches up grabbing a fistful of sheet in one hand and a fistful of her father's pubic hair in the other. she pulls mightily.

most anti-nude arguments deal with the scaring or scarring of children. they lack merit. a handful, even a three year old handful, of short-hairs viciously ripped from their root is merit, big ole wail-in-the-night merit.

editorial clarification: this man was not me.
