In a comic for Team Fortress 2 called "Blood Brothers", Redmond and Blutarch Mann both agree on a truce on their war over gravel pits so they could build a machine to get one of them pregnant, seeing as neither had an heir. Additionally, in the comic "The Naked and The Dead", the Medic from the game told the Heavy from "Team Fortress Classic" he had put 3 baboon uteruses inside him, and upon pressing a button (which was actually just a pen), they’d develop into fully developed baby baboons.
