Try me!

Why don't people who has no knowledge (aka retards) listen to the real professionals in the arab world?? A question I always ask myself whenever some dude pops out and tries to show his "powerful" science techniques to me. People would rather listen to friend or someone who tried that before rather than listening to professionals. There is a common proverb in egypt that says " Ask someone who tried not a doctor" totally ridiculous !! then people would come over later complain about their stupid consequences
