C is dangerous like your uncle who drinks and smokes. Y'wanna make a weedwhacker-powered skateboard? Bitchin'! Nail that fucker on there good, she'll be right. Get a bunch of C folks together and they'll avoid all the stupid easy ways to kill somebody, in service to building something properly dangerous. They'll raise the stakes from "accident" to "disaster." Whether or not it works, it's gonna blow people away.

C++ is dangerous like a quiet librarian who knows exactly which forbidden tomes you're looking for. He and his... associates... will gladly share all the dark magic you know how to ask about. They'll assure you, oh no no no, the power cosmic would never turn someone inside-out, without sufficient warning. They don't question why a loving god would allow the powers you crave. They will show you which runes to carve, and then, they will hand you the knife.
