Jerk or acorn?
If you fall down after reading this sign, the sign already calls you an "eikel".
For the Dutch viewers this makes sense for the other I'll try to explain.
In the Netherlands we call a jerk or stupid person an "eikel". But the seed of the oak, the acorn we also call "eikel". The double meaning of the word gives made me see the sign in a different perspective.
