I have an IQ test. Attention the question:

25 is True or false last statement?

All the ships are penguins, and all penguins have grass-cutting machines on their feet; in addition, some penguins eat refrigerators; and all fanatics eat refrigerators. But none of those on whose feet grasshoppers grow is a dryer; so no ship is a refrigerator.

The hurry! The purest truth.
