National Lampoon's Christmas Vacation (1989) is the third installment in the National Lampoon's Vacation film series. Clark Griswold has decided to host nearly his entire extended family at his house for the holiday season, including his parents, his in-laws, his senile old Aunt Bethany and, eventually, possibly-inbred cousin-in-law Eddie. As can be expected, everything goes horribly wrong in the most hilarious way possible. A perennial Christmas classic, and notably the only one of the Vacation series to take place at the Griswold home. Had a Made for TV Movie sequel made in 2003.
