Big Fish willfully misinterprets German sentences into dirty English phrases. Jaja and I were practicing German in the car, and every once in a while Big Fish would interrupt with a "what did you say?"
My favorite interpretations were:
Schmect gut ---> Smacked her good.
Guten Tag ---> Good and tug
Guten Nacht ---> Good nobbin
Richtig ----> Lick dick
Danke schön ---> Donkey shin
