BIC and SKI

I like to learn skills that require dexterity like juggling, pen tricks, and butterfly knife tricks (see http://sculptorbyday.blogspot.com/2010/11/its-computer-science-time.html on my twin's blog).
Today I was flipping my pen, and I saw that it said BIC on it. I've been thinking about combinatory logic recently, and all of B, I, and C are well known combinators. The word BIC reduces to the combinator that swaps its arguments, which is called "flip" in Haskell.

Therefore, BIC pens are the best pens for pen flipping tricks. QED.
