Dennis the Menace - S01EP10 Dennis Yard Sale/The Abominable Snow Menace/Planet Dennis

When Henry and Alice leave to go to a "Poor People's" charity auction, Dennis decides to help the poor people by selling most everything in the Mitchell household. Mr. Wilson, who is supposed to check on Dennis but arrives late, is shocked when he sees what Dennis is doing. So, he and Dennis go on a madcap scavenger hunt throughout the neighborhood to retrieve the pieces Dennis has sold before Henry and Alice get back home. By the time they get back with all of the pieces, Henry and Alice arrive with lots of "new" junk. So much so that Henry declares that maybe they should hold their own auction! Wilson falls down in exhaustion. Vacationing at a ski lodge, Dennis and Joey cause so much chaos that the manager dresses as a snow beast to scare them off. But when the beast gets into trouble Dennis rescues him and the guests vote for the boys to stay. Dennis and PeeBee, in an effort to help Dennis clean his room, decide to build a robot to do it for them. Once built, the robot escapes and causes havoc throughout the neighborhood. Mr. Wilson, who is being bothered to cut the lawn by Mrs. Wilson, thinks it's a creature from outer space and gets caught up in the chase. In the end, Wilson finds out that it's Dennis' creation and gets the bright idea of using the robot to cut his lawn!
