The older I get, the smaller my cubicle gets. In fact, I don't even have a cubicle now. But my boss used to walk in undetected and catch me doing research for some assignment (WWW - to the boss it looked like web surfing) and he would tell me to get to work. I wanted to put a cowbell around him, but I'm sure he wouldn't go for it, so I had to come up with something else. (note - the title should be "Flatulent.")
Step 1Picked up this nifty noise maker for about 6 bucks in the toy section of the food store.

You can read the package for yourself. It has about 6 different random "tunes." But, the key item is the little RF remote button that comes with it.

The latest Iraqi trick is the shaped charge handgrenades. They *really* pack a punch!
Think about it - if the situation was reversed, would you *ever* give up? Nor will they!
The problem with such asymmetric warfare (30 a month on the US side, vs. 30 a day on the Iraqi side) is that the places you are occupying have no option but to turn to terrorism and guerilla warfare. It's evolution, because anyone dumb enough to try to stand and fight is dead already. No-one stands and fights an M1 Abrams with a few stones if they can help it. The only ways to win are to kill everyone, or leave. The killing everyone option seems not to be working, so why not use the other option, and leave?
With that out the way, on to the topic at hand.
The new shaped charge hand grenades are stick grenades, with a small trailing 'chute, to try and get them hitting head down onto the armour. There are some great videos of them on YouTube. Genuinely shaped charges, and as such they have to interface the target armour at the right distance and angles to be effective.
RPGs are totally different things, warhead aside.
The sticky bombs you mention were invented by the British, and they were very sticky. They weren't shaped charges, though, they were simply a HE head that exploded. To be honest, they weren't very effective, but they were designed for the Home Guard guys as much as anything, to give them some hope of beating a tank. But since they weren't even issued with ammo, generally...
The electrical defence is actually quite simple, but genius. Insulate a metal plate 1" off from the armour, and whack a big capacitor across them. Charge it up.
When an RPG or other shaped charge hits the plate, the charge fires a (usually copper) slug of molten metal through the first plate at around 3000m/s. Think of this as your fusewire. As it reaches the actual armour and starts to penetrate, the capacitor discharges very rapidly through the conductive path opened up. This turns our fusewire into a blown fuse, and the light spatter of molten metal that hits the armour is, of course, easily stopped.
Again, have a look on YouTube, there is a video on there of a UK light armoured car being hit 10+ times by RPG7's with almost no effect.
=P Creativity at its finest.
