Random Question (and answer)

This was my random profile question, but it said that my answer was too long, so I am posting it here.

Sponges and tongues are frequently misspelled. Is it because both are thirsty?

It is often hard to think straight when our bodily needs have not been met. So for those with inferior powers of concentration it would be almost unbearable to try to write either of these words because immediately upon hearing either one of them, I suppose that their tongue would swell up and then all they would be able to think about would be the misery of their discomfort. And the worst part is, when you get part of a sponge wet and try to use it, it's likely to tear, so then they would be trying to figure out how to get all of their tongue wet at once, lest the same fate befall a dear member of their own body.
