I ate at a fast food two days ago. I attempted to speak only in German, but then the guy behind the counter asked me if I want a "special menu something-something with something", so I got confused and I instinctively switched to English, asking "what exactly is that?". He then answered, also in English: "This one on the left comes with the big cock (pointing towards a COKE bottle), this one on the right is with a small cock. Do you need a big cock, sir?".
The guy was really confused as to why me, my friends, and the random American-sounding guy left of me were almost pissing ourselves laughing.
