Beware of jealousy

IAGO:
Oh, beware, my lord, of jealousy!
It is the green-eyed monster which doth mock
The meat it feeds on. That cuckold lives in bliss
Who, certain of his faith, loves not his wronger;
But, oh, what damnèd minutes tells he o'er
Who dotes, yet doubts; suspects, yet soundly loves.

William Shakespeare - Othello (3,3)

Iago on women

IAGO:
Come on! Come on! You are pictures out of door,
Bells in your parlors, wildcats in your kitchens,
Saints in your injuries, devils being offended,
Players in your housewifery, and housewives in your beds.

William Shakespeare - Othello (2,1)
