Nylabone Headstand

Tahoe loves to chew the end of his nylabone on the living room floor...  
Kathy asked me, "Did you stand Tahoe's bone up on the floor?"
I replied, 'What??"
Kathy said, "Come look at this bone."
It appeared as though Tahoe arranged the bone for a prompt return to his chewing activity when he returned from checking on what was going on in the backyard. 
So strange, to say the least, to have the nylabone standing up supported only by the velcro-like action of the chewed up nubs on its end..
