Static utility class?

Hi all!

Example code:

<https://gist.github.com/mhulse/6441525>

Goal:

I want to have a "utility" class that contain utility methods which should
have the option of being called multiple times on a page.

I think my main goal is to avoid having to "new" things ... I don't really
need to create an instance here (there's no need for a constructor in this
case).

Question:

Is the above simple pattern a good way to have a class that calls static
methods?

To put it another way, is there any reason why I would not want to use the
above code?

Basically I want to wrap these simple functions in a nice class wrapper and
have the ability to call them without having to jump through more hoops
than is necessary.

Are there any pitfalls to writing a class like this? Or, is this the
standard way of writing a simple "utility" class for this type of situation?

Please let me know if I need to clarify my questions.

Thanks for your time?
