Description
By now bored with the successes of our own standard model, cosmologists
yearn for evidence of something new, indicating, e.g., that dark energy 
is not a cosmological constant, or that the primordial density 
inhomogeneities have unexpected statistical properties.  Recently 
there has been excitement, feverish in some quarters, about the 
possibility of extra species of neutrinos.  I will tell the story of my 
own few-month-long bout with neutrino fever.  I will pay particular 
attention to signatures of neutrinos in the cosmic microwave background
while also weaving in some evidence from reactors, accelerator-created
neutrinos, and observations of Helium in extragalactic gas clouds.
