Methinks what happened is Hakuba did his own laundry.
While he was tired.
And added a purple sock to the whites.
Don't ask me why he has a single purple sock.

Or he's colorblind. *blink,blink* That'd be interesting. My dad's colorblind and thinks purple=blue, so maybe he thought he was going blue, blue, green? But, my dad also thinks sometimes that green=yellow, so it begs the question, why was he going to go with blue, blue, yellow? *walks off, still thinking it over* Of course, that's asuming he's red/green colorblind...
