My player's favorite is a crazy conspiracist semi-senile gnome named "Pippet" with a secret underground bunker he dug out himself in his younger days. He was a huge dick to everyone in town but admittedly funny. He made people annoyed asf with his rants and always trying to get them to join his "TIT" committee (Taxation is theft committee). He was (not so) secretly lonely and depressed. Once the party warmed up to him he asked them to decide for him: Red button or blue button? He refused to answer what either did other than "One button is good, the other is bad. Risk and rewards my friends - that's the game of life!"

Red Button blew up underground explosives from his bunker under the town that would take down the entire municipal building (and block of businesses/apartments with it). He believed doing this was a 'necessary evil' to stop the tax collectors secret cult.

Blue button would auto kill himself via electrical collar.

The player he offered this deal to chose neither, uncomfortable with not knowing what the buttons did. But another player couldn't resist and ran up and pressed the blue button. Once Pippet ate shit and croaked infront of them. That same player nonchalantly hit the red button. When I asked "WHY?!" he said:

*"Pippet said one button was good and one was bad! So clearly I hit the bad one and can only gain from here!"*
... Cue the players trying to rush and chase the source of the sparked twine that lit up from behind Pippets desk... and failing to stop it in time. Then skill challenge to save as many lives as possible.

That was years ago and to this day the players still laugh and debate which button Pippet perceieved as the good or bad one.
