@lightweight Reminds me of one (bulgarian?) joke:
A policeman (traditionally all policemen are very dumb in Bulgarian jokes) sees a man in the sidewalk, selling something.
- what are you selling?
- apple seeds
- apple seeds?
- yes, they make you smart!
- really? How much are they?
- 5 euro for 2 appleseeds
- ok. I'll take 2.
The policeman pays. Takes the seeds and eats one of them. Than says:
- Wait! For 5 euro I could have gotten a kilogram of apples!
- Well you see - You've eaten just half the dose and it already works!
