This is great! It articulates what most of us programmers feel internally when we're interrupted. What's I'd also love to see is a cartoon explaining the external effect of an interruption. Like, when you interrupt a programmer you're pulling the "stop" cord on an assembly line: it doesn't just effect that individual, but there is a net effect on the overall effort. (FWIW, I don't think the assembly line is a good example, because programmers work in parallel, not in sequence, but it's the best sort-of-example I could think of on a Monday morning...)
