Move Over, Griswold, the Light Heavyweight Is Back! — Dave’s Diary [Video]

National Lampoon's Christmas Vacation has inspired thousands to push the limits of illumination.  Some take it farther than others!

A New York state family reclaimed the Guinness World Record for most Christmas lights on a residential property. Tim Gay said he had no plans to attempt a record this year until the makers of Ritz Crackers donated an installation featuring about 200,000 lights, bringing his total to 601,736-lights.

The record was certified by Guinness when all 601,736 lights were illuminated simultaneously for the required 10 minutes. Not to be outdone, previous record holder David Richards set up a display featuring more than 1.2 million bulbs at a Canberra, Australia shopping mall. (USA Today)
