Is it just my Lucy or...

Do all dogs feel the need to put their chew toys on some part of your body to chew on them?  Cause Lucy does it all the time.  Usually my feet.  The other day on my arm and she misjudged and bit me instead of her toy.  Oh yea and a few times she has put them on my boobs and I was like no way!  About the time she misjudged on that one she would have been in so much trouble!!  But tonight she is driving me crazy (okay crazier then normal!) because she is insisting on using my foot as her toy holder and her nails, which I just trimmed the other day, are killing me!  Why?  Why?  Why?
