Only You Can Coin

Only you can, can see this
Only you can, you can coin
If you’re there and nothing
Else can coin on you
If you can, cannot can.
And if you can’t, it’ll ask you
That you can’t, you can’t.
But you’ll ask back, that you’re not
As only can.coin can.
A joke is this on English
Hard to under stand
If one can can’t than one can’t can
But coin can can again ..
What can’t isn’t an answer.
