[side-bar] One of my all-time favorite songs is Signs by the Five Man Electrical Band. Verse one of the song goes as follows.

```   "And the sign said long haired freaky people need not apply
So I tucked my hair up under my hat and I went in to ask him why
He said you look like a fine upstanding young man, I think you'll do
So I took off my hat I said imagine that, huh, me working for you"
```

[another side-bar] You approach an office door and the sign says...

```   Back in 5 minutes...
```

5 minutes from when? 1 minute ago? 4 minutes ago? May be a moot point given a 5 minute time frame, but what if the sign says...

```   Back in 25 minutes...
```

Now the question gains importance: 25 minutes from when?

Back to the number `5`... `25` is a perfect square because the square root of `25` is `5`.
