My friend Luther Bangert is a wonderful person and has had an exciting life. As the title states, he's a Guinness Record holder, tied with Space Cowboy for most balls juggled while swallowing a sword.
But he also memorized pi to a lot of digits. Not a Guinness record level of course. There are some really pi savants that have done it to like 100,000 digits. But still, he's a fascinating person.
