I did naked floss in my car and my dog started barking at me like I was a weird alien.
My brother does naked floss every time he comes home from work. He says it's his way of saying 'I'm back.'
I did naked floss during a movie and the guy behind me turned around and asked if I was doing a weird kind of dance.
