Let me ask you a brain teaser: a group of frogs are taking a bath in the pond. All frogs are naked, but one of them is? Guess.

Because all other frogs are skinned and turned white, only it is green ~

The second possibility is that all other frogs are crazy, and it doesn't, so it wears green clothes!

It is also possible that the frog's pond is out of water ~

The fourth is that it is shy and afraid to take it off.

It may also be because everyone else is male, only she is female ~ so the man and the woman grant it or not!
