Happened to me during a North American interview some time ago ...
CAPT: So, do you like beer ? Would you drink a beer on an overnight ?
ME: ( Thinking what do I say to this one ) ... Of course I like a beer or two. As long as there's plenty of time on the overnight.
CAPT #2: Don't worry about him, he just wants to know if someone will go out drinking with him.
