Friendship Algorithm T on Amazon

Is it just me, or is The Big Bang Theory ripe with casual clothing-ready ideas. We've seen the Rock-Paper-Scissors-Lizard-Spock/Knock-Knock-Knock Penny! T-shirts, the Bazinga! Hoodie and now we get The Frienship Algorithm T-shirt.

One more thing to add to the Knerd-Must-Have-Now list.
