Famous quotes containing the words check and/or digit:

    The veto is a President’s Constitutional right, given to him by the drafters of the Constitution because they wanted it as a check against irresponsible Congressional action.

    Gerald R. Ford (b. 1913)

    Bless my soul, Sir, will you Britons not credit that an American can be a gentleman, & have read the Waverly Novels, tho every digit may have been in the tar-bucket?
    Herman Melville (1819–1891)
