There was an excellent example along these lines in the RubyConf '04 
blogs.  According to Francis Hwang's blog:

"Also, Rich [Kilmer] described a cool little hack: Adding time-unit 
methods to Fixnum so you can write code like time_to_restart = 5.hours 
+ 15.minutes. Dude, I'm totally stealing that."

I have to agree with the entry, it's a killer trick.
