I just received an email telling me someone has commented on the one video I’ve ever posted to YouTube (being the conclusive cake-cutting in the Scissors vs Pizza Wheel experiments).
This guy calls me a ‘jerk-ass’ for not using a knife. I think he’s missed the point.
Plus, what stupid insult. The jerk-ass.
[See here for the video in question.]

http://xkcd.com/202/ is quite apt, I feel.
Your experiments intrigue me, I’d only ever used a pizza cutter to cut pizza before today…
Indeed - I like XKCD
