• it's no joke

• have one's wits about one

• scare him out of his wits

• thrilled to bits

• at one's wits end

• hit score a bull's eye

• get it straight

• worth its weight in gold

• it's touch-and-go whether

• it stands to reason

• frighten him out of his wits

• give it short shrift

• it's and ill wind that blows nobody any good

• it's early days

• a split second

• it stands to reason that

• lend itself to it

• it's a toss-up whether

• serve its turn

• if the shoe fits

• it's a small world

• do the splits

• let it slide
