Mario, according to a 3 year old.

Plumbers make good money.

Seriously. Tradesmen make as much if not more than doctors. If your kid aspires to be a plumber than you should support them because they'll absolutely be able to take care of you when you're old. Besides making good money, a tradesman like that can take on apprentices so they don't even need to work themselves, haha. The life a plumber is a good life.

Also, little boy is adorable but I want to throw him out a window for his comments about the PS3. Or maybe just shake him, Michael Jackson style.
