Apostrophes
One final pet peeve concerning apostrophes incorrectly used with plurals.
Almost all plurals that are not possessives do not use apostrophes.
Use PCs, not PC’s.
Use TVs, not TV’s.
Use tacos, not taco’s.
Use hundreds, not hundred’s.
Use pizzas, not pizza’s.
Use “Way to go, Vikings!” not “Way to go, Viking’s!”
Exceptions are the plurals of letters and numbers.
There are two s’s in that word.
She dots all her i’s and crosses all her t’s.
My son can say his 1′s, 2′s, and 3′s in five different languages.
Three posts are more than enough to spend on these misused apostrophes and might even cause you to join this group:

Lets discard the apostrophe. Its pointless.
Apostrophes
Apostrophes (‘) are used for three reasons: possession (boy’s bike), contraction (don’t) or omission (Rock ‘n’ Roll). Today I’ll cover contractions and omissions.
For both contractions and omissions, the apostrophe replaces the missing letter.
Contraction examples would be:
you’re for you are, where it replaces the a in are
it’s for it is where the apostrophe replaces the i in is
Omission examples would be:
gone fishin’ where the apostrophe replaces the g
pot o’ gold where the apostrophe replaces the f
rock ’n’ roll where the apostrophe replaces the a and d in and
In a date when part of the year is left out, the apostrophe needs to indicate the missing year. In the 80s would mean the temperature; In the ‘80s would mean the decade.
Apostrophes
Apostrophes (’) are used for three reasons: possession (boy’s bike), contraction (don’t) or omission (Rock ’n’ Roll). Today I’ll cover possession.
If the owner is singular, add the apostrophe before the s. The boy’s book.
If the owner is plural, add the apostrophe after the s. The girls’ sleepover.
If the owner is plural without an s, add ’s. The women’s room.
It the owner is it, do not add an apostrophe. The court said its decision was fair.
Do not add an apostrophe on plural words that are not possessive. The dogs barked.
