What thou see’st when thou dost wake,
Do it for thy true love take.
Love and languish for his sake.
Be it ounce or cat or bear,
Pard or boar with bristled hair,
In thy eye that shall appear
When thou wak’st, it is thy dear.
Wake when some vile thing it near.

– William Shakespeare

A Midsummer Night’s Dream, Act 2, Scene 2. Oberon chants this spell as he squeezes the love potion from the enchanted flower into the sleeping Titania’s eyes. She will fall in love with the first creature she sees when she awakens. He mischievously wishes that it is some "vile" creature, like a wildcat, bear or wild boar.
