That and, depending on the stylebook you use, some specific words and uppercase letters that could be considered confusing when pluralized, like “Oakland A’s” and “Do’s and Don’ts” (according to AP, while I much prefer Chicago’s guidelines).

Most sources online will say “don’t do it but some people do by mistake.”

Also acronyms, again depending on whom you ask. At least based on my own instincts and online searching.
