On our German tests back in hs, there was a vocab section where we'd use words in sentences. I didn't know one of the words in one of the tests, so I wrote "ich weiß nicht was bedeutet", which means "I don't know what means". Our teacher accepted that one with a laugh, but said it was a one time thing and it would not be allowed again. People still tried their luck with similar tricks after that, but got nothing.

Me, I was just surprised she'd never seen that in her career before. I wasn't expecting to get any points for that. Thought she for sure would have had other smartass students like me.
