Haha! To cute! Yorkies will teach you to put your clothes away, use a laundry hamper, and close the closet doors, lol! (oh and drawers too)
Peek a Boo has no preference, clean or dirty is fine with him. I don't know how many times I have found him in a laundry basket, napping! He hasn't really stolen anything, but when he is laying on clothes, do not try to remove them....you will risk losing your hand!
