Yes, but...
There was one evening lo, these many years ago, when my wife had me tied down by the wrists only. She left the room to get something to eat. By the time she came back, about 10 minutes later, I had folded my legs up to my wrists and untied myself with my toes. She thought I was still tied down.

That was the evening I really found out, I just don't make a good sub.
