Conversation reported on Twitter by (who is Dutch and working in Belgium):

Collega 1: Wel spijtig dat jullie nu op zondag moeten zingen dat jullie de prinsen van hispanje altijd geëerd hebben.

Collega 2: Ja, maar anders hadden ze moeten zingen dat ze van Duitsen bloed waren.

This is not worth translating, but if you know the Dutch national anthem and have been following the World Cup (and I know that some readers do fall into both categories) you may find it quite funny. (As long as you hadn’t already heard it.)
