It's a major magic mantel
That you stand beneath to brace
And it's more than just a marble shelf
Above the fireplace
It's a mainstay of a mantle
That you two are balancing
If you don't maintain this mantel
You dismantle everything
For it's propping up the chimney
Which is holding up the walls
Which are making up the rooms
The nooks, the closets, and the halls
Which are shoring up the flooring
Which is bearing up the stairs
If you don't keep up the mantel
Then prepare to make repairs
Keep it up, keep it up
Keep it up and don't be lazy
There's a weighty fate upon your little shoulders
Keep it up, don't let up
Lose your marble and go nutty crazy
You are the designated mantel holders
The mantelpiece supports the house
The house supports the sky
The sky supports the galaxy
So on and by and by
When this mutual supporting meets
The no returning point
Time and space are intersected
Where infinity's detected
To be endlessly connected
To the cosmos by a universal joint
So support your local mantel
Friends, it all depends on you
If you don't there is no telling
What the universe will do
We're so gratified the two of you
Have risen to the task
Which may take a while
Eternity
How long is that?
Don't ask
Keep it up
Keep it up
Don't let it down
