    I could SWEAR that Samuel Clemens a.k.a. Twain said it somewhere.
    
    One quote that does come to mind: "I must have a prodigious amount
    of memory, considering the amount of time it takes me to make it
    all up."  (From 'An American Abroad')

|  |     To "have in mind" or "bear in mind" is to have in one's memory, to
    remember. To "put [a person] in mind of" is to remind someone, to cause
    that person to remember. 
    
    The OED, which provides the earliest known instance of each word or
    phrase, quotes one Jehan Palsgrave, 1530: "I will put hym in mynde of
    his promesse." 
    
    The OED says this may have developed from an obsolete usage, to
    "come [a person] in mind," to occur to one's recollection. It quotes
    Chaucer in 1374: "And every word gan up and down to wynde, That
    he hadde seyd as it come her to mynde."
                   
    The American Heritage lists this usage as "informal," while the
    OED does not.
