G'day Bruce

Upstairs in Gogarty's playing G'day Bruce.
Because this is a great laugh, here's how it works. Players stand in a circle and everyone is called Bruce (to begin with). Player 1 turns to Player 2 (to his left) and the game begins:
P1: G'day Bruce (to P2)
P2 replies: G'day Bruce
P1 replies: Say G'day to Bruce(P3), Bruce(P2)
P2: G'day Bruce (to P3)
The game continues until someone messes up and then their name is changed by the other players. Then is starts to get difficult. Obviously alcohol consumption raises the enjoyment of the game.
