Arrrrgh, I cant remember the name of the film, but here goes anyway.

"Tell that bitch to shut up before i come over there and fuckstart her mouth"

Anddddddddd...Monty Python and the Holy grail is too quoteable by far...but...
"Shut up you manky scots git" springs to mind As does..."I think I'll go for a walk"..."Youre not fooling anyone you know" (Bring out your dead scene) (filmed entirly in Scotland I will have you know)
