German Joke

Professor Mason concluded his PrePort talk on Germany with this joke:

Angela Merkel (the German Chancellor) was making her routine visit to
Greece, because their economy is doing so poorly. She had just landed in
Greece, and like the rest of us, had to go through Customs. At Customs,
they asked the usual questions:

Customs: "What is your name?"
Angela: "Angela Merkel."
Customs: "What is your nationality?"
Angela: "German."
Customs: "How long is your stay?"
Angela: "One week."
Customs: "Occupation?"
Angela: "No, not this time. I'll only be here for a week."
