Quaids -- Another Day, Another Court No-Show

If you're counting, this makes for the fourth time Randy and Evi Quaid have failed to show up to court in Santa Barbara ... and this time, it's double their fault.

The Quaids -- who have been accused of running out on a $10,000 bill at the San Ysidro Ranch -- actually requested their case be put on the court calendar today ... and still didn't show up.

After their third no-show last week, the S.B. prosecutor told us he was filing papers for them to be extradited from Texas, where they live.
