Okay, guys! I brought this idea to the attention of chaperoned and she agreed that it could be useful to the community. It was partly inspired by this, and this. So, let's play a little game. It's called TOTALLY LOOKS LIKE. In this game, you basically make a family of PBs — those people who look like they could past for brother/brother, sister/sister, cousins, etc. If at all possible, you can also suggest which families/fandoms they work for! When we've compiled a big enough list, I'll put them into another post that you can refer back to.
