Bluemoon 

Intelligent computer oriented woman

with an un-ending desire to see a certain someone in their "Birthday Suit."

Moonie, you might as well give it up...

I doubt any of us are ever gunna see MacGrad in his "Birthday Suit."

Besides, he says he sent it out for cleaning and that it has "stripes" ~
