Edward's Turmoil (2009)

A reluctant grandfather had the chore of taking his grandson, Edward out to lunch. Grandpa is a foul-mouthed old curmudgeon and Edward is a bible loving neurotic mess. They're stuck spending the day together and they hardly know each other. When grandpa accidentally says the F-word to a passing car, he discovers something peculiar about his grandson. He is tormented by swear words. Edward becomes a shivering, quivering wreck whenever someone swears. Grandpa is bewildered and amused by all this and takes it upon himself to cure what he thinks is a very unfortunate ailment.
