Insanity is my calamity

When madness spreads like peanut butter, do we know why?
Because pigs fly?
Or was a cow jumping over the moon?
Are you a looney toon?
I think I am. Maybe I'm Roger Rabbit, meeting Alice in Wonderland, going down a rabbit hole.
Ribbit, ribbit, the frogs says, but "That's all folks" says Sam to Bugs Bunny.
Alice and Sam, Roger and Bugs. What a life they lead.
Where are they going? What are they doing? When will they return? Why did they leave?
