• knock him for six

• not on your nellie

• I would not put it past him to do it

• dawn on him

• not to have a leg to stand on

• at a rate of knots

• not up to much

• up in arms

• not before time

• horn in on it

• not bad

• an olive branch

• not to be able to call one's soul one's own

• not to be able to see the wood for the trees

• not for love or money

• that's not my pigeon

• knock off

• not quite right in the head

• not to have a snowball's chance in hell

• last but not least

• an oddball

• not to have the faintest

• down on one's luck

• not much to look at

• bear down on it

• not in the same league as him

• lean on him

• knock around

• the game is not worth the candle

• get in on the act

• be up in arms
