Silly fun at my library job.

Sometimes you have different duties, including shifting books across massive spans of shelves in order to open up more space.

As could be expected, that's called "shifting," and sometimes you're told to "shift" books.

So, one day when I was told to do that for my entire shift at work, I kept telling people, "You know what I'm doing today, a 'shift shift'!", and I kept laughing, and I kept trying to use the word "shift shift."

People were pretty amused; I think the job's repetitive, so supervisors appreciate stuff like that.

I also wanted to joke that it would be fun to wear a tutu and cha-cha on your shift shift, but I didn't.
