Laff is your health on Toontown. Your Laff Meter tells you what your max Laff is, and how much Laff you have left. Every toon's max is at least 15, and the highest max you can have is 137. The only way for your current level of Laff to decrease is for a Cog or some other obstacle (such as a stomper or lava) to damage you. If you lose all of your Laff, you will go "sad" and be sent back to the nearest playground. Your toon will lose all of it's gags, be hunched over, walk very slow, and not be able to leave said playground until your Laff is at least 1. It's not recommended to leave with only 1 Laff point though, since virtually any attack will send you back to the playground, sad and gagless.
