Is it possible to boil an egg in the microwave?
Ideally without having to pierce the shell first

Be careful putting whole eggs in the microwave. A relative of mine was burned on her face (fortunately not severely). After removing the egg from the microwave it exploded.
It's possible to blow open the door of your microwave if you try it on high for too long. For best results, watch it from about a foot away.
I decided to post this as an answer instead of a reply to @AttilaNYC . I think you're better off just boiling it. I'm a big of fan of doing and cooking stuff fast; however, eggs are too perfect and to lean to do that. Boil the damn water, dump your egg in it until it's done. I don't love, but I like this site.
I've been using the Nordic Ware Microwave Egg Boiler for a few years. Depending on the size of the eggs, you'll need between 6.5 and 8 minutes at 1100 watts. Once you've settled on a brand and size of eggs, you can get them perfect every time - hard boiled, soft yolk etc. by tweaking the cooking time between those two values.
Fantastic gadget, 4.5+ stars on Amazon with over 1200 reviews.
I feel especially strongly about the grossly understated and potentially life-changing danger of doing so, there is no exaggeration. I speak from personal experience, not it-happened-to-someone-I-know.
Don't risk serious burns and high speed flying egg shell fragments JUST DO NOT TOY WITH THIS at all; I had and it was just luck that I did not end up losing my sight, just blistered eye lids and face.
If you must use a microwave, heat a big bowl of water ALONE WITHOUT EGGS (put some baking beads in the water to minimise superheating). Then take the hot bowl of water out of the microwave and put the eggs into the hot water to cook. Wrap the entire bowl with a thick towel as insulation to preserve the heat. You do not need to maintain a boil or water at close to boiling point to cook eggs
Water makes up nearly 90% of egg white and nearly half of egg yolk. So an egg is >75% water. Microwave cannot distinguish between water in a container and water in the egg and just heat one part preferentially or selectively. Fats in the egg yolk also have dipoles capable of absorbing microwave for heat conversion too.
I have heard that you can wrap each egg in a piece of alum. foil, being sure all shell is covered. Put in a micro safe dish with water to cover fully or preheat a sufficient qty of water then add eggs. The foil prevents the microwaves from penetrating the shell and causing exploding eggs. The water is supposed to prevent arcing.
Timing would depend on amt of eggs and water, and whether you preheated.
*WARNING* I HAVE NOT tried this myself, but it sounds reasonable
I admit I haven't tried this in the microwave, but it should work and avoid the exploding-egg possibility altogether.
What you would do is, take a large microwave safe container - the larger the better, really. Fill it with water, though leave room for the egg(s). Heat the water until boiling hot. Carefully add your egg, and leave it in the microwave, door closed, until it's cooked - how long will depend on your ratio of egg to water and how cooked you prefer it, but to give an idea four eggs would take about a half hour.
The hot water cooks the egg, and since, beyond heating the water, the microwave is never actively aimed at the egg it won't have an opportunity to explode. The technique would work even if the hot water is kept, say, on the counter - though the residual heat in the microwave, and the insulation of its walls, will help keep the heat up so the egg cooks faster, in the same way turning off the stove but keeping the pot on the still heated surface keeps the heat up a bit.
If you use the same container and roughly the same amount of water each time, you should be able to figure out pretty precisely what works in your microwave with a little trial and error.
Put a microwave safe bowl in the microwave with just enough water to cover the eggs, but don't put the eggs in yet! High setting for 1.5 minutes till it boils, Add about a tablespoon of vinegar and a tablespoon of salt. This will keep the eggs from cracking and will make them easier to peel. Add the eggs and cover with a dish, but leave a slight gap for steam to escape. Medium setting for 8 minutes (check after 5 minutes to see if there is still enough water covering the eggs, some microwaves are more powerful than others. Take out the bowl and let it sit for another 5 minutes or so and you should be ready to peel and eat...
