You've probably already seen the video demonstrating how easy it is to peel a head of garlic using two bowls, but here's another method to try. All it takes about 20 seconds and a microwave.
Heat a head of garlic in a microwave for about 20 seconds and the cloves will slide right out of their skins with no mess and no sticky garlic juices. This tip reminds me of a similar trick that uses the microwave to shuck corn — so now I'm looking around the kitchen wondering what else I can peel with the help of my microwave. Chickpeas, perhaps?
