Back in the 90s the Hungarian society was shocked in its foundation by a new product they advertised on telly. It was the toilet duck, a cleaning chemical sold in a plastic bottle shaped like a goose neck.
The idea is that cleaning part of the toilet hidden by the rim isn't easy (other cleaning apparatuses were invented too to solve this problem), and with the curved neck of the toilet duck, one can just squirt the cleaning agent to the area.
Now today it's one of the most common things to buy similar stuff, that ridiculous design mostly was left behind, or reserved by that one product as signature mark. Probably kids born in the 90s can't remember the times when no such things existed. Back then it was funny. Even made joke about it.

One kid to another:
- We have toilet duck, are you jelly?
- No. We don't shit under the rim.
