A Number Too Big for Your Head

Here's an interesting skit about Graham's Number g₆₄, the largest number ever to appear "constructively" in a mathematical proof (except maybe for g₆₄+1). The part up front about why it wouldn't fit into your head is also clever:


Mathematicians really are some of the most interesting people I have ever met. In graduate school I fell into a crowd of them during my last year, and it was the most probably the funnest year of my whole life. (Somehow, I managed to get my thesis written too.)
