Invent a time machine by accident

where are these blueprints?

I made the machine, fired it up, but it would only take me back to my schooldays – where Eddie Fitzpatrick got me in a headlock and rubbed his knuckles on my head.

You get so much hope up for these things, and then they turn out like this… There’s a very important lesson here folks..

but I’m open to stumbling over something and finding the blueprint..
