Ahmadinejad to Bush - SUCKER!
There is a basic concept in street fighting that if a potential adversary is bigger and more powerful than you, the first order of business is to get that adversary off
guard, then smack him in a vital spot so you can bring him down to size.

The best way to do this is to appear non-threatening, even friendly if necessary, and get close enough to land a sucker punch. An even better technique is to take a two-by-four and hit the big guy across the shins, which inevitably bends him over in extreme pain, which gives the smaller combatant a clear opportunity to hit again, harder.

If you just want to get your adversary's attention, you hit him with the flat edge of the board, which hurts, but spreads out the pain over a wide area. However, if you really intend to inflict some damage, you try to land a blow with the sharp edge of the board, which means a far more concentrated, and far more incapacitating encounter...
