Those Meddling Kids: 25 Hours of Doo was a special 25-hour Scooby-Doo marathon that aired on Cartoon Network from 12:00 PM, Saturday October 24, 1998 to 1:00 PM, Sunday October 25, 1998. The marathon ran on the day the clocks moved back for Daylight Savings, adding the 25th hour of the marathon.
During the marathon, eight retrospective interviews featuring the gang, spoofing MTV's The Real World, aired during commercial breaks. These segments later ran as program fillers on Cartoon Network and Boomerang, and were included on the VHS release Scooby-Doo's Greatest Mysteries.
Unfortunately most of these videos cannot be viewed here and must be viewed directly on youtube.
