A while back, I was in my home office watching a TED talk by Sally Kohn where she described herself as a "talking head."
My daughter, who was on the other side of the desk and could not see the screen, ran over to my side of the desk and asked incredulously, "She's a head?"
Knowing my daughter's thought process (and having a sad flashback to the mini/Minnie hot dogs debacle at Disney World when she was younger), I patiently explained that a talking head is someone who expresses their opinion on television, not someone who is actually a disembodied head.
Crestfallen, she shrugged and said, "well, that's a letdown" and returned to her side of the desk.
Although frankly, that's a TED talk I would like to see.
