Last weeks episode of The Big Bang Theory had Sheldon arguing with Leslie Winkel. His response to her insult follows. I just loved it.
Sheldon: Yes, well, I am polymerized tree sap and you’re an inorganic adhesive. So whatever verbal projectile you launch in my direction is reflected off of me, returns in its original trajectory and adheres to you.
Translation: I’m rubber. You’re glue. Whatever you say bounces off of me and sticks to you.
