Sometimes it's clever to be stupid. Like when you're caught up in a tricky situation where you're uncertain what to do, and not sure what the right answer is. So what do you do? How should you handle things? Try to be clever and bluff your way? Make a great pretence at knowing all the answers, when it's perfectly obvious you haven't got a clue?

Of course not, unless you want to make an even bigger fool of yourself. When in doubt the best defense is - to simply act stupid!
