Inundated With "It's"

Sorry, but this persistent error -- I think I've seen it a dozen times now over the past week here -- is really making me lose my composure.

(Seriously.)

"It's", with an apostrophe, is a contraction for "it is". Just like "he's", "she's", and "they're".

The possessive form for the word "it" is "its", with no apostrophe. Just like "his", "hers" and "their".

Enough said, I hope.
