Dogbert stands on a stool watching as Dilbert fixes what looks like a time machine. Dilbert says, "My invention will let me search the service industry's space-time continuum." Dilbert is seen in the machine travelling through a galaxy with several floating workmen. Dilbert says, "Plumber, roofer, carpenter, electrician." Dilbert stops and looks at one worker and says, "Weren't you supposed to fix my furnace in 1991?" The worker replies, "You're my next house."
