This man is trying to do something less usual!
He has a strange idea about the fact that big fish can be found in the city sewer.
He doesn’t waste the time and prepares himself to demonstrate its theory.
He brings everything and starts fishing. After a while, guess what happens?
His theory becomes true after he catches a big fish. After releasing it, he tries one more time and catches another one!
It seems that the chances were pretty high, even more than he expected.
