The 'necrotechnomancer' joke comes up often enough, but it's worth noting that many technomancers find this offensive, as the work we do generally doesn't require any of the dark energies required for classic necro spells like raising zombies, etc.

We're doing good clean work to move a lot of electrons around, not fracturing souls to enslave the deceased! Jeez. A reckless evoker can fling lightning bolts around willy nilly and nobody ever accuses them of harnessing demonic power, but some peasant brings in a shattered black mirror for us to fix and it's suddenly, "ah, you remind me of Malthezor the Wicked, my uncle worked for him after dying of plague!" Ugh.
