How do you make your crush laugh/flirt across the room with a guy you like?

I have my guy friend in my class who I like and we talk some. But i can't just walk across our classroom to flirt %26amp; talk. So how should I get his attention %26amp; flirt/make him laugh in class?How do you make your crush laugh/flirt across the room with a guy you like?
It kind of depends how close the relationship is between the two of you. If you have a lot of inside jokes or you know a lot about you, then you could make notes to him that are funny and include those things. Or you could still write him a note but just with different things. If you don't like the note idea you could just crack a joke with him after class and be like ';I was trying to get your attention';


I hope I helped.(:


P.S.


I kind of have the same problem but a little different.
