When I last visited Berlin, I heard a joke about the airport's problems that I thought was very funny: "Niemand hat die Absicht, einen Flughafen zu errichten!" ('Nobody has the intention to build an airport!') Context: https://en.wikipedia.org/wiki/Berlin_Wall#Construction_begin...
The other popular joke, after all these years and billions spent: "Let's just move Berlin to a functioning airport"
"Did you hear about the new grammar reform? It includes a new tense, Futur III, to allow us to speak of the completion of Berlin/Brandenburg airport."
