Some games don't need plots. Some games don't try to have plots. For lots of earlier games, a plot wasn't even necessary.
But, over time, video games have evolved as a medium, and it has since become almost necessary to have some semblance of a story. Some games just shove it to the side, do it simply so that it doesn't get in the way of the game (Super Mario Galaxy comes to mind). Others have embraced the newfound capability of telling a story within the medium (Phoenix Wright, most JRPGs, so on and so forth). Sometimes, they're better off without.
So, what's the worst plot you've encountered in a game? The overall quality of the game is irrelevant here; a game can be great but still have an incredibly stupid plot.
A really bad one that springs to mind is the recent Sonic the Hedgehog game on the PS3/360. Confusing time travel nonsense that relies heavily on the <a href=http://tvtropes.org/pmwiki/pmwiki.php/Main/TimeyWimeyBall>Timey Wimey Ball, a furry romance story, and cut-and-paste plot events add up to something that can only be described as incredibly stupid. The fact that the underlying game sucks doesn't help matters.
