I Feel Mysterious Today

Always cause for concern
When you're feeling quite bright
And your filament burns
I feel mysterious today
Everything is humming loudly
I feel mysterious today
Everything is coming this way
Is it ever appealing
To stand on a ceiling?
Observe the tension grow
Going walking abroad
Minus hat before dawn
Bats in profusion there
Did you ever conceive
That you too can leave
Exactly when you like?
