You know that I know
But not about to let on
To the secret of the secret handshake

It's been around for years
Barely above a whisper
As most take it to their grave

No one knows where it's from
It's just been here all along
Comes in different models and makes

Has a manual to please
In invisible ink
So the secret's not given away

You must swear on an oath
Not to let the truth go
To do so would be a mistake

Sounds mad as a hatter
But it's no laughing matter
The secret of the secret handshake
