Sausages: Tasty and delicious, although too many can be bad for you. Made of little bits of things that aren’t necessarily tasty on their own, but blended together they’re awesome. Can be purchased in packages, or (for the enterprising) made on your own. Eating the same sausages gets old after awhile.
GMing: Lots of fun, although too much of it (especially without also playing) can lead to burnout. Involves a variety of activities, both before and during games, that aren’t always fun on their own (for me, that’d be prep) — but when blended together, they add up to awesome. Adventures and sourcebooks can do some of the heavy lifting for you, but you can also do everything on your own. Never varying your style gets old before too long.
