"The real troubles in your life are apt to be things that never crossed your worried mind, the kind that blindside you at 4 pm on some idle Tuesday."
— Kurt Vonnegut
Ironically, the expenses themselves may be unexpected, but the occurrence of them is very predictable. For example, here's a late fee that I just got:— Kurt Vonnegut

I wish I hadn't gotten this, but things fell through the cracks with my book launch. After learning this the hard way a few times, I decided to get proactive about unexpected expenses.
I've set up a sub-savings account and now save about $150/month for unexpected expenses. (Note: You can start with $20/month and work your way until you find the right amount.) At the end of the year, I sweep the account, taking any extra that's still in it, and move it over to my "general" savings account.
In your savings account

These sub-savings accounts are incredibly useful for focusing your savings. It's easier to save for specific goals rather than a guilty, "I should save" account.
Book excerpt: Unexpected income & expenses
From Chapter 4 ("Conscious Spending") of my new book, where I describe how to handle unexpected income and expenses:

We all have unexpected expenses each year. But if you look back, you'll notice a pattern: Car repairs, Christmas/birthday gifts, or last-minute travel. Given enough time, these "unexpected" expenses are fairly predictable. Start saving—even $20/month—to get ahead of these expenses. When they arise (and they will), you'll be prepared.
