A great idea

We’ve got a great idea

Not like the last idea

Which turns out

Was not such

 a great idea

in fact we’ve learned

was a bad idea

you could say

we had no idea

how bad an idea

the last idea

was not a good idea after all

but we’ve got a new idea

a much better idea

and I think you’ll find

this is a really great idea

which we will look back upon

and say how clever we were
