Poor Herbert looks a bit nervous about being introduced to so many people. Either that or just surprised because he was unexpectedly possessed, either way.
And hey if all the Herberts come here to downvote it must mean they got accounts if they didn't already have them which means mission accomplished right ;D
Herbert the Horrendous is socially awkward. And yes, this was just a ploy to get more people to sign up. I'm sure it's working.
