Once a Knight Is enough

Posted by Ian Phemister on December 23, 2006

I have a sticker on a heater box of my Morris Mini Cooper S that I recently purchased. It dates to around 1970. It reads...."Once A King Always A King, Once a Knight Is enough". What does this mean??? Where does the saying come from??? Cany anybody help.
Thanks
