As a child I habitually had a blocked nose, which meant I usually had to breathe through my mouth. I used to think that if I were able to breathe through my nose, not only would I be able to breath air, I would also be able to breath under water. I evidentlly believed that all nose breathers could breathe under water. I tried it once - it definitely didn't work!! :-)
