Yeah, sometimes they get funny ideas from toons. I've found out I can 'defuse' those situations by joining the narrative and then going full on Roahl Dahl and suggesting something outrageous, which in turn puts the kid into a mode where they figure things out on a more philosophical level. I actually say things like "Yeah, the princess has a nice castle. I'm sure her father sure enslaved lots of people to build it" and they go like "that's horrible! No, um, let me think... I'm sure it was built by paid professionals!" Etc. Kids don't get damaged if you insert a little bit of cognitive wiggle room to their favourite narratives :)
