Ribs

Rock was at his big brother Jim's house and thought it was strange that his brother had used a raw rack of pork ribs to serve in place of a broken leg on the Habachi grill that sat in on his kitchen table. It kept the grill from wobbling, but seemed like an odd choice for the job.
When Rock returned several months later, the same rib was in place supporting the grill, though it was now thoroughly cooked. Rock asked about it. Jim laughed and said he would have to come up with a better, more permanent solution.
All the while it seemed perfectly reasonable to both that Jim sometimes cooked on a charcoal grill inside his kitchen.
