Time Tunnel

Gonna build myself a tunnel
that I can travel through.
It'll work just like a funnel
that goes wherever I want it to.

I'll learn a little science.
Brush up on the arts.
Build a cutting edge appliance 
free of gears and moving parts.

Not a simple time machine
like H.G. Wells created,
but the best thing mankind's ever seen
once it's demonstrated

that it's anywhere at any time
and straight back home again.
Once I build my tunnel
I'm on my way back when.

Or maybe I could borrow,
if I promised to return it,
some knowledge from tomorrow.
Bring it back and learn it.

Might be a cure for cancer.
With this tunnel I'll design
any question I could answer.
Any object I could find.

Like sunken Aztec gold.
I could visit history.
See if Judas really sold
out Christianity.

But I've no time for guilt.
I'm such a busy guy.
Once I get my tunnel built
I'll teach myself to fly.
