Mad Professor Blyth is working on his pet invention
To dematerialise himself into the fourth dimension
He's got his mind set on illusion
To find the secrets of diffusion
Conclusion: he disappeared

Tried it on his cat one grey night when it was foggy
Never got it back Oh what happened to his Moggy
He's got his mind set on illusion
To find the secrets of diffusion
Conclusion: he's disappeared

All the kids around about his neighbourhood
Used to laugh at him and call him names
Silly old bat freaky four-eyes

Sort of things they used to shout
He can't hear them now

He's disappeared

Colleagues at the lab
They all thought that he was crazy
Don't know where he's at
His formulas to them are hazy
He had his mind set on illusion
He found the secrets of diffusion
Conclusion: he's disappeared
