 I don't know that I know a particularly bad engineering joke, but I heard a lot of engineers tell fat jokes. Everything is locally linear, but I mean, I'm doing it sure that's a joke. To be honest, I don't know. I don't have answer for that. High equals three. For example, if you're like a scientist, you'll probably be concerned about like the ninth, tenth, eleventh, twelfth decimal. Well, if you're an engineer, you oftentimes like you would have your like margin of safety or a factor of safety. Oftentimes like close enough is good enough. No need to spend another million dollars to find that level of precision. So that's why high equals three. I don't think engineers are particularly enough for the humor.
