Say I have a hash like so:

```
top_billed = { ghostbusters: 'Bill Murray', star_wars: 'Harrison Ford' }

```

What would be the best way to format it in a nice, human-readable way?
For example if you called a method on the hash and it displayed the hash as a capitalized list, minus underscores.

* "Ghostbusters: Bill Murray
* Star Wars: Harrison Ford

I guess iterating over the array and using gsub to remove underscores then capitalizing might work, but I was wondering whether there was anything more elegant.

Thanks
