A quote from a Monty Python
sketch. Used whenever someone is trying to speak a foreign language to you, but they're either doing it wrong
or you don't understand.
A Hungarian tourist goes into a cigar shop looking for a box of matches, but doesn't speak English, so he brings a badly-written phrasebook with him. When he tries to ask for matches, he ends up saying "My hovercraft is full of eels?"
Tourist: "Ah, ah, my hovercraft is full of eels?"
Tourist points to matches: "My hovercraft is full of eels!"
Clerk picks up matches: "Oh, this?"
