FROG: How you English say: I one more time, mac, I unclog my nose towards
you, sons of a window-dresser, so, you think you could out-clever us
French fellows with your silly knees-bent creeping about advancing
behaviour. (blows a raspberry) I wave my private parts at your aunties,
you brightly-coloured, mealy-templed, cranberry-smelling, electric
donkey-bottom biters.
