A Sack full of Simples Finds its Way Back

I was walking along on the railroad track

When I stumbled upon what looked like a pack

With a sack full of simples and samples and tack.

I went next to a shop, and there on the rack was a similar pack

With a sack full of simples and samples and tack!

Now how did the sack get up from the track and make its way back

To the shop with the rack?

I studied the matter both forward and back,

And I came to believe there’s a bit of a crack

In the fabric of time that provides for some slack

When a shop with a rack in the back

Has a serious need for a pack with a sack

Full of simples and samples and tack!
