When I was small I used to watch The Land Before Time a lot. The theme song is 'If We Hold on Together'. Some of the lyrics are:
If we hold on together
I know our dreams will never die
Dreams see us through to forever
Where clouds roll by
For you and I
I somehow heard those lyrics (with a mangled tune to match) as:
Blazing motels
One thousand is the total
Waltzing at once
And we'll do it again
I believed this for a very long time. I knew it never made sense but accepted it as fact anyway.
