Happy face + light bulb = applause.
Oh boy, I can already tell I’m going to be bad at this.
The philosophy produced by healthy happy persons is enjoyed by Faust.
If you’re happy and you know it clap your hands? 
Outstanding!

Good one, Xun.
I was gonna say “The Rise and Fall of Shy Chicks”, but it’s too many words.

'Nuff said? 
Its actual title is a bit longer than three words.
Origin of Species.
(That was a long way to go for “orange”.)
