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) the femur, relatively speaking & money lent to purchase a flat bottomed cargo boat
2) a molar, relative to position & a kiosk where small short nails can be purchased
3) an overcast period of time & unstylish pottery raw material
4) a stupid pyramid occupant & a silent ventriloquist partner
