• have one's ear to the ground

• easier said than done

• as fresh as a daisy

• as easy as falling off a log

• make a pig's ear of it

• have a word in his ear

• you can't make a silk purse out of a sow's ear

• go easy on it

• have his ear

• a flea in one's ear

• zero hour

• work like a busy beaver

• zero in on it

• easy on the eye

• take it easy

• a nosey parker

• easy come easy go
