I learned to spell and pronounce it with a "D" like God intended. I know this, for in the Lost Book Of Moses it is clearly stated that while upon the mountaintop, God kinda messed up writing on stone and put in a "well, it works" patch. God his own self said to Moses, "Well, it's a kludge, but it'll work for now." And Moses responded, "So, then, the adjectival form would be 'kludgy', nu?" and God replied, "You got it." (Lost Book of Moses 23:12-37)
