Tetris: five cheesy ads to celebrate 25 years

It's been 25 years since Alexey Pajitnov, then a 29-year-old artificial intelligence researcher, came up with Tetris while working at the Soviet Academy of Sciences in Moscow. "A quarter of a century later," the Guardian reports, "it has a legitimate claim to being the videogame that has truly conquered the world. In all its forms, Tetris has sold more than 70 million copies around the globe; it has spawned architecture, art and music; it has earned multiple Guinness World Records; and is regularly voted one of the top games of all time." It's also enjoyed its share of goofy ads. Here's five of them. Other brands have gotten Tetris fever over the years, too. For example: these bizarre spots for Honda and Toyota.
