Why does my papercut have yellow stuff in it?

I cut my finger on a pack of pencils (plastic) and it bled and now it's all hard and there is yellow stuff in it and it is bruised all along the edges.

The cut is infected... get some Hydrogen Peroxide, squeeze the cut until it oozes, and then soak it in the peroxide for 10-15 min. Dry it, and then put an airtight bandage on for a few days.
