How the mentally handicapped make the possesive form of "it".

Idiot: Your computer has one problem - it's case.
Non-idiot: My computer is a case? It's more than that.

(1) It is.
(2) It has.

N.B. Not to be confused with "its," which is the possessive of "it."

(1) Contact. It's the answer.
(2) It's been real slow 'round here since the new sheriff arrived.

WRONG: The dog wagged it's tail.

Ohhh, if you want it to be possessive it's just 'its,' but if it's supposed to be a contraction then it's I-T apostrophe S!

Scalawag.

It's = "It's gonna blow!"
Its = "Its fangs are seven feet long."

Contraction for "it is".
NOT the possessive form of "it". Like "yours", "hers", etc., the possessive form of "it" is "its", with no apostrophe.

Yes: "It's a rabid dog."
No: "Be careful of it's teeth."
