Bring a large pot of water to a boil over high heat. Add the corn and cook for 10 minutes. Remove and set aside to cool. Once cool enough to handle, slice the corn off the cob.
Heat a large pan over medium-high heat. Add the corn to the skillet and cook, stirring often until lightly charged and sizzling. Remove and set aside to cool.
In the meantime, cook the pasta in the same pot of boiling water that was used to cook the corn. Cook until al dente, approximately 1-2 minutes less than the package instructions. Drain and rinse well with cold water. Set aside.
In a large bowl, whisk together the buffalo sauce, mayonnaise, and sugar, then add the cooled pasta, corn, shredded chicken, celery, green onions, and cheese.
Just before serving, gently toss in the avocado and serve with minced chives, blue cheese crumbles, and a dash of buffalo sauce if desired
