Made this comic last year for Comic Party http://comicparty.dk/ which is why you get two comics about German/Danish relations in a row.
Anyway, when Denmark briefly got a bit of it's border control back last year (stopped 1 in 100 cars or something like that) the Germans didn't just complain that it was against European agreements, but also took it as a very personal attack on them, probably because Germany is the only country connected to Denmark by land.

Well, Germans do like to invade their neighbors. And dig holes.
