I found this on another forum
You know you are addicted to RuneScape when:
You go into a bank and shout "Dance Party!!!"
You go to England, see suits of steel armour and think, "noobs..."
The treacher says where's your homework and you reply "I sold it for 5gp"
You go fishing lobbies during your breaks at school
You shout "Oh my! Totally PAWNED and 0wned j0o noob" in the middle of a maths exam
You walk past a church and say, "Prayer n00bs!"
