Silent E by Tom Lehrer

Who can turn a can into a cane?
Who can turn a pan into a pane?
It's not too hard to see
It's silent e

Who can turn a cub into a cube?
Who can turn a tub into a tube?
It's elementary
For silent e

He took a pin and turned it into pine
He took a twin and turned him into twine

Who can turn a cap into a cape?
Who can turn a tap into a tape?
A little glob becomes a globe instantly
If you just add silent e

He turned a dam - alikazam! - into a dame
But my friend sam stayed just the same

Who can turn a man into a mane?
Who can turn a van into a vane?
A little hug becomes huge instantly
Don't add w, don't add x, and don't add y or z,
Just add silent e
