Can someone give me a quick and dirty explanation of what neutrinos are and how they operate in the universe?

Neutrinos are little bits of practically-nothing that the universe uses to balance its books. Whenever an interaction occurs in which angular momentum would not normally be conserved, the universe tosses a neutrino onto the table as a way of making change.

Look, you *said* you wanted quick and dirty!
