Ern picked Hey Arnold (pictured), because Ern can still watch and enjoy that, to this day. Leeard refuses to play any Facebook games that are not Bejeweled Blitz (Ern and Leeard have a fierce-ish Bejeweled competition going, usually). Ern's sister picked Ahh! Real Monsters. We've seen some Disney princesses, Doug, Dragonball Z, and Rugrats.
We have not confirmed why people are doing this. It's either to promote awareness regarding child abuse or to celebrate your favorite childhood shows.
We wonder how long we are supposed to keep the pictures up. We wonder a lot of things about this new trend. We like the celebrities thing better, but this is cute too.
If you are reading and changed your picture, let us know what you picked.
