NEVERDOUBTILOVE

Doubt thou the stars are fire;

doubt that the sun doth move;

doubt truth to be a liar;

but never doubt I love.

O dear Ophelia,

I have not art to reckon my groans;

but that I love thee best,

o most best...

Believe it. Adieu.

It was a quote from Hamlet in the eighth episode in the second season of Joan of Arcadia, after the character named Judith died, due to a stabbing attack. He was in love with her and she made the deal with him that if he knew all of Hamlet off by heart, she would go on a date with him. She considered it to be more of a joke, a goof, but he took it seriously, because he really liked her. After she died, he recites this bit of Hamlet, which proves that he knew the entire play, completely off by heart, just for her.
