For the sake of those who don't know.

This is referencing an old game called facade, a 'dialogue' game in which you help 2 people overcome hidden aggression toward each other, blah blah happy ending.

The thing is you can only 'talk' to them and pick up various things around their home, and you can get thrown out if you insult them or act weird enough for a long enough time. For some reason or another 'melon' is a trigger word that makes them automatically flip their shit and throw you out immedietly, there is a reason for this, but i've written long enough already.

TL:DR,
1. go to youtube
2. search Facade Melon
3.watch a video or two
4. ???
5. lol
