La famiglia Mezil

...but about half of the jokes have their meanings only in Hungarian so it might be really hard to translate it into English.

The Unique Adventures of Mézga Family is about a family where the son (Aladár) invents lots of stuff (well, like Dexter in his laboratory but in a less idiot style) and gets in contact with his great-great-greatson from the far future. In each episode, they try to solve some (quite simple) problems not by solving them by common sense but by asking for special future objects, machines etc to help - and of course, they get in a much bigger trouble...

The first spin-off series was about The Adventures of Aladár Mézga, who made a spaceship for himself and secretly travelled to space in every episode. The second spin-off series was The Mézga Family on Vacation where the Mézgas were invited by Hufnágel Pisti (see in the review below) so they travelled across the world in 13 episodes. I don't even understand why these masterpieces can not be found here on imdb...
