I think I've cracked it (almost)
1 for each 'pretend swearing' (Mutha Uckas could be hazardous)
2 for each time Murray reveals his poor musical knowledge
2 for each time someone mistakes them for British people
1 for each time Eugene buts in on a conversation
Turkeys =3 drinks
Jemaine keeping Bret up with silly questions= 3 drinks
Actual swearing (aside from Dave) = 3
Maybe the clothes stuff as well?
Not full drinks, just sips...
