What does it mean when your crush say this?!?

[May]

My crush "he knows that I like him" posted it on twitter... I think he was pointing at me in this..

Can you explain what does this sentence mean?!
And when do you actually say it?!

"Some people get confused if a sentence does not end as they potato."

And what does it mean when your crush say that to you? I, honestly, didn't understand his point..

P.S: I was posting things about one-sided love/crushes and quotes about girls who like guys, who don't care about them.

Actually, his body language shows that he likes me.. he always stares at me and smiles whenever he sees me, he can't take his eyes off of me..
But, at the same time, he talks to me rudely on facebook.. and always ignores me..

He's confusing me.. so I don't wanna think that he likes me, so when I found out that he doesn't I don't get shocked..

P.S: He's my brother's friend..

Do you think he likes me?!

I think it means that he does like you.

I think every single word in that sentence indicates that he likes potatoes.
