Unfortunately, bricks do not lend themselves easily to St Valentine's Day, so this scene from a Shakespeare play (not even from Romeo & Juliet!) will have to suffice:
Act 4. Scene II
SCENE II. Blackheath
Ay, there's the question; but I say, 'tis true:
The elder of them, being put to nurse,
Was by a beggar-woman stolen away;
And, ignorant of his birth and parentage,
Became a bricklayer when he came to age:
His son am I; deny it, if you can.
Nay, 'tis too true; therefore he shall be king.
Sir, he made a chimney in my father's house, and
the bricks are alive at this day to testify it;
therefore deny it not.
