Here's a local body art place I blogged about: Do's & Tattoos. I'm not exactly sure what the rule here would be. Technically, to indicate the omitted letters, it would be 'Dos. But I think there's a rule that says if the result is unreadable, you can put an apostrophe in the plural to make it read better. Without the apostrophe, people 'round here would read it as "dos"; i.e., the number two. So, it would be . . .
'Do's.

Here's a link to the blog post, if you're interested (but no biggie):

I'm a professional writer. I know all about apostrophe abuse.

It hurts me. Personally. And I'm not timid about letting those around me know of my pain.

My mother swears she will never write anything to me again. :D

My mother can write to me without tadpole trouble. So can Dad.

My younger brothers' elementary-school English instruction was all fucked up; they never got any phonics and aren't the spellers or the tadpolers I am.

You didn't stress the first syllable?

And yeah, B. Sports is an adjective modifying teams. None of the teams are in the possession of a genetic variant.

ha! I got some nasty comments about my blog post. But no one but me seems to care about the blatant apostrophe abuse! Sad, sad state of affairs.

Now you know who the nits are.

Oh, come on! How about the Mutant Denver Bronco's from HELL?
