When I look at my friend's posts on Facebook, it shows how many comments there are to each post. Yet when I look at the comments, there is always one short. Why is that?

You could block the respective user(s).
Blocking allows you to prevent most interactions with someone on Facebook. People you block won't be able to find you in searches, view your profile, or contact you with pokes, Wall posts, or personal messages. In addition, they will not be able to see your Wall posts, comments on mutual friends’ Walls, or that you are a member of the same group as them.
However, this might not work in certain situations:
Why am I able to see content added by a user that I've blocked on the site?
Blocking a user will prevent any type of direct interaction between you and that user. However, for technical reasons, there are certain instances when an individual you have blocked from your account may be able to view your comments on the site and vice versa, including comments on a mutual friend's photo. Please be assured that your listing will appear in black text, with no profile picture visible or contact links available.

Facebook has comment spam filters that will, by default, hide certain comments (unless the post owner goes in and manually unhides them). The comments remain in the comment count but don't show up to the public (if it's your post you can see three dots and click to manage the spam posts).
I'm not sure if there is an official list of what's spam-worthy according to Facebook, but as an admin of a very busy page here's what I've found that gets hidden:
Anything in all caps
A single emoticon multiple times (e.g. <3<3<3)
Significant repetition of characters (e.g "Cool!!!!!!" or "aaawwwwwwwww")
Sometimes (but not always) a link without any additional caption or comment
This happens on my FB page all the time (cute dog pics tend to elicit these types of responses) and you won't be able to un-hide the comments unless the post is your own (or you are the page admin).
