A reference to the song 'Ik ben vandaag zo vrolijk' by Dutch singer Herman van Veen: http://www.youtube.com/watch?v=zXNETrbtnpI
Your "correct" sentence has a typo: nooi. It marked me incorrect because i wrote "nooit"
Great, now I have this song stuck in my head.
Shouldn't "... ik was nooit zo vrolijk" also be accepted?
