 Two men pretended they wanted to open a hole in the sky and thank Bobbi-Bobbi personally.They hurled the rib-boomerang and tore a huge hole in the clouds which startled Bobbi-Bobbi so much that he failed to catch the boomerang which fell back to Earth and killed the foolish men.This was the first time that Death had visited the human race, so Bobbi-Bobbi has remained aloof in heaven ever since, making no more attempts to help humans.
