For the uninitiated: "The United Federation of Hold my Beer."

Yes, that explains what Humans bring to the table: sheer, ill-informed, unbridled, un-jaded, undistilled, optimism.

It also explains why Voyager sports bio-neural components that can't handle cheese, why 1701-D is comically oversized compared to its crew compliment, why outfitting the entire Federation fleet with recycled Borg tech got the green light, and why bridge workstations have a failure mode that kills the operator with heavy-metal concert pyrotechnics the moment it's shaken too hard. Nobody told them they couldn't do that, so they did.
