Out of the originals I can't seem to think of anybody!
Nobody normal would follow me around many different forums over the best part of 20 years till I fuck it all up.
Though I'd say that @Pedro has always been the most normal and the most mature. That's not saying much though.
But from the newer members I'd probably say @Tango and @Motobiker.......though they'll eventually end up as imbeciles I'm sure.
