Spontaneous Combustion: Signs and Symptoms?

I'm curious to know if there are any signs and/or symptoms that would give warning to spontaneous combustion.  If you know of any, please feel free to leave a comment below as I believe I might need to be on the look out thanks to Jeremiah.  Everyone button of mine has been pushed, and I am sure that there were several button casualties along the way as they were pushed so severely that there was no hope of recovery.  As for my sanity, well, may it rest in peace.  I'd list all the things that have occurred today to get me to this point, but I would like to leave my computer sometime in the next week so I won't.  Let's just say that my sweet Jeremiah is a go getter who goes all out in everything he does...including disobeying. 

I should probably go lay in the snow and cool off as a precautionary measure.
