HOMER WONDERS WHO HIS REAL FATHER IS ON "THE SIMPSONS" SUNDAY, JANUARY 8, ON FOX

William H. Macy, Joe Frazier and Michael York Make Guest Voice Appearances

Marge's rage against the new toll road system somehow leads to the discovery of a frozen mailman and his 40-year-old mail. The letters are returned to the rightful recipients, including one to Grandpa Simpson's deceased wife, revealing a secret love affair and the real father of her baby, Homer. Confused and emotional, Homer finds Mason Fairbanks, his wealthy and much improved paternal dad, and happily establishes a father-son relationship with him while rejecting his surrogate father of 40 years. But soon Homer realizes that a DNA test doesn't necessarily tell who his true father is on THE SIMPSONS episode "Homer's Paternity Coot" Sunday, Jan. 8 (8:00-8:30 PM ET/PT). (SI-1703) (TV-PG L, V)
