@edensaesthetic Sonnet 130 begins:
My mistress’ eyes are nothing like the sun;
Coral is far more red than her lips’ red;
If snow be white, why then her breasts are dun;
If hairs be wires, black wires grow on her head.

The second line is not strict iambic pentameter, because you cannot say "co-RAL", only "CO-ral". But Shakespeare wrote it anyway because it sounded better that way. Stressing the first beat instead of the second in that manner is called "inversion" or "substitution".
