Funny conversation I overheard while buying groceries ..

Person 1: why is it, programmers always seem so sad, negative.. Depressed?
Person 2: well, the less you know the happier you go.
Take a look at retards.

Person 1: sigh. I want to be happy.
Person 2: Remove your lust and you're left with happy.

Person 1: wut?
Person 2: look at that retard over there, shouting happy by itself.
Person 1: I see. But how would I apply it.

Person 2: well, I don't think shouting like that retard requires much application.

Person 3(me): don't worry, be happy.
