This dates back to 2007, when Sylvia Lavin explained how when she was a child, she used to visit Art Museums with her parents, both Art Historians. While they studied the artworks, she would study and mimic their gestures, getting ready for her fruitful career as a critic. At what moment did dildos and other useful household utensils finally enter the equation is something that needs further exploration.
No, no pun intended.
