Tense Tension

To:  Editor of "The Record"   (should one exist):     
       The present tense of the verb is plead; the past tense is pled, or pleaded.  The past participle is pled or pleaded. 
        Please refer to last  week's lesson, which was  lead, led, led.  The other  word spelled "lead" but pronounced "led" is a noun meaning a metallic substance, or ammunition.    Please go over your notes; someone may read what you wrote someday.
   P.S.  Stylistically, as to the alternate usages of the past tense of plead, either pled or pleaded is grammatically correct, though you may want to use "pled"  as in , "He pled his case before the judge,"  but he "pleaded with the judge for leniency."   ( Yeah, I knew you wouldn't care.)
