There once was a dog who ate a sandwich. The dog enjoyed it very very much, so he got another one. He ate to his heart's content
He forgot he had high blood pressure, and high cholesterol. The dog had a heart attack. He was then sent to the hospital...but it was too late.
He was then sent to doggy heaven. He had so much fun there, that he forgot about his sandwich. He never wanted to go back to earth again.
Minutes later he woke up confused. He was in the hospital. It turns out he was bought back to life with chock therapy. Doggy wanted to go back to heaven.
Doggy killed himself on the spot, by injecting himself with protein he found next to his food. He died in a matter of seconds. Doggy didn't go to heaven this time, he didn't go to hell either. Instead he was just a spirit.
Doggy couldn't eat a sandwich anymore because he can't eat, he's a ghost.
A poor soul, wandering for all eternity.
