Exploding head syndrome!

It's just one of a number of unusual things.

And what do "My Head is Spinning," "Now, Stand Back For Your Own Safety!,” "Okay I'll Admit That I Really Don't Understand," "Schizos (Are Never Alone)," "Television Rules the Nation," "That Tastes Horrible," "Egg Sandwich," "Thermonuclear War (Is Good For Your Complexion)," The “Batman” theme song, and "Pennsylvania 6-5000" have in common? (Answer here.)

Actually, I think I experienced exploding head syndrome once. If you don't know what it is, you may be saying, how could you possibly have it more than once, and, moreover, why are you still here?
