Germination, my favourite way is to plop them in a cup of water for 24 hours, this will get water inside the shell. If the seeds are good they will either be on the bottom by the end of the 24 hours, or you can give them a poke and they will fall to the bottom. If they're bad they'll float. Some good ones will go half way down or so and then come back up. They act differently than the duds though, you'll know
After that put them in a moist paper towel and put it in a ziplock on top of your TV, leaving the TV on for heat. The water inside will speed the germination up and they'll crack within another 24 hours.
