Things I learned from Slenderverse

Marble Hornets: Don't try to help your friends, they'll probably die and it'll be all your fault. Also don't film yourself.
EverymanHYBRID: Never exercise. Ever.
TribeTwelve: When in doubt, grab a knife and yell "FUCKINGCOCKSHITMOTHERFUCKINGFUCKERBITCHFUCK."
DarkHarvest00: Stay out of the fucking cults.
All the other series that are awesome: If you think it's someone pranking you, it probably isn't.
The beta game Slender: There's no such thing as bad attention. (but yeah the series came first and his name isn't actually Slender. it's not actually that scary, pipe the fuck down and play Slender: The Arrival when it comes out)
