Hey pal, you're not helping. It's hard enough trying to finish a grueling 26-mile race without having to defend your mother's honor against cheap shots from a randomly placed (though admittedly clever) insult comic elf. We also didn't appreciate this guy's other signs, like "Triathlon? More like Try-harder-athlon," and "I could win this 5K if I was fleeing from the sexual advances of your extremely overweight sister." (That last one took up a whole banner and actually blocked a portion of the roadway.)
