Question

[Neapolitan Ice Cream]

If you plugged up your nose and mouth right before you sneezed, would the sneeze go out your ears, or would your head explode?

Well, your head would not explode. I do believe that the pressure would be forced to your ears and you could blow-out an eardrum, or you could end up "swallowing" it. I don't think it'd be fun in any case.
