I jutify doing it by making sure I save all the little seeds for a tastey and healthy snack. A lot of people roast pumpkin seeds....everyone does it a different way. Here's how I do it:
While you are gutting your pumpkin, put the seeds in a bowl full of water as you go. Pull off all the big chunks of goo, but don't worry about the rest of the slime- it will come off in the water.
Let the seeds soak for about an hour, then, when you are ready to bake them, pour them into a strainer and rinse well.
Roast on 350 for about 15-20 minutes, stirring every few minutes. When the seeds start to brown, they are ready to be taken out of the oven. Make sure the seeds are completely dry when they come out. If they still feel wet, they're not done.
