A spoonerism is a pair of words that can have their initial sounds switched to form new words. The pairs need only sound the same, not necessarily be spelled the same (power saw & sour paw, horse cart & coarse heart). There may sometimes be one or two connecting words (kick the stone & stick the cone, king of the rats & ring of the cats). Given the following definitions, what are the spoonerisms?
1. A lashing device in Athens & a feeble grasp
2. The source of a leaky kettle & why a vaulter would need to wear oven mitts
