The mother of all apostrophes

It is Hallowe'en.

Respect the apostrophe, love the apostrophe, use the apostrophe correctly. Given how Hallowe'en is spelled (and it is a little tricky to remember), all PRs should make this the one day of the year when they vow to change their ways by learning how use apostrophes correctly rather than continually embarrassing themselves with poor English.

Enough now.
