If you had punctured your eardrum at some point, you would have known it, my husband did it once, it hurts like a motherfucker and then you can, literally (if you smoke) blow smoke out of your ear for a while.
However, if "stuff" gets in there, where stuff can be anything from skin cells to pieces of a paperclip, it can easily form a tumor. This tumor can spread to your brain and you will die.
Now go to a fucking doctor and get rid of any paperclips around your home and office.
