"If aspirin gets rid of pain and headaches"

non-aspirin gets rid of non-pain and non-headaches...

but what are non-pain and non-headaches?, they are aspirin.

therefore, non-aspirin gets rid of aspirin...

modus ponens, modus tollens, whatever...

now, I have a headache understanding this, so don't give me a non-aspirin.

If someone is inept, it means that they are not capable of performing a specific task. But nobody can be "ept" because there is no such word.

If water is "ice cold" wouldn't it be solid?
