The anime made the initial crossover even better. Those bastards even took advantage of the fact the Gintama episode aired first to steal Sket Dance's joke about the voice actors. They even revealed they cast Shiraishi Ryoko as Jugem all those weeks ago specifically for that; that's some planning
The concept of a devil fruit that turns only your crotch into a hammer as a side-effect and Gintama schooling the Sket Dance kids about the danger of the Gintama world for one's crotch was hilarous. The dirtiness of the jokes is part what makes Gintama so much better.
