Press the Random Button for a random result.

I'm pretty sure it won't do anything, its connected to the end of the panel.

I'm not totally sure, but from the artist's commentary I think that's supposed to be the doorbell to someone's house.

Added translation, either that or something like "Ju... just pushing..."

Or a 'Don't Push the Red Button' and she push then Boom? I mean Red Button is synonymous with you know....Cold War paranoia?

i'm reminded of The Pointless Button from asdfmovie lol
