I was crazy once.
It starts with 'Crazy?' and never ends. It's like being stuck with a million rats in a rubber room for life.
My sister sent me a message: 'Crazy? I was nuts once.' I replied, 'I was stuck with rats.'
My friend kept repeating 'Crazy? I was nuts once.' until I had a headache.
My classmate kept saying 'Crazy? I was nuts once.' like it was a spell.
