Spazy Croonerisms 3

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) punched when starting work & discussion about scaling a mountain

2) a container of fibs & a shortage of baked goods

3) hasty vacation & prank gibe

4) a mongoose & artificial precipitation
