I'm Going **Slightly** Mad

When the outside temperature rises
And the meaning is oh so clear
One thousand and one yellow daffodils
Begin to dance in front of you - oh dear
Are they trying to tell you something?
You're missing that one final screw
You're simply not in the pink my dear
To be honest you haven't got a clue
I'm going slightly mad
I'm going slightly mad
It finally happened - happened
It finally happened - ooh oh
It finally happened - I'm slightly mad
Oh dear!
/.../
It finally happened oh yes
It finally happened
I'm slightly mad!
Just very slightly mad!
And there you have it!

Дам, без съмнение ключовата дума е slightly;).
