Hulk share story now. Listen to Hulk. Very sad story. Papa Hulk, he fight from wheelchair. Very awkward. No polio vaccine in days of Papa Hulk. He drown in swimming pool. Polio bad. But before die, Papa Hulk made sure Baby Hulk, me, get vaccine. Before, polio, diphtheria, measles, mumps, rubella, rampant. Now, no. Hulk apologize for typos and grammar. Hands too big for keyboard and mind consumed by rage. But message still clear. Disease bad, vaccine good.
