During the entire history of Saturday Night Live, there have been good hosts and hosts that have been alright. But there has also been hosts that have been terrible. They made this list of bad hosts for one of many reasons. One, they just weren't funny and were awkward. Second, they aren't really well liked or well known, which also makes it less funny. But mostly because they weren't funny.
Here is a list of the top 5 horrible Saturday Night Live hosts in the 2000's:
Derek Jeter hosted SNL on December 1, 2001
Taylor Lautner hosted SNL on December 12, 2009
Al Gore hosted SNL on December 14, 2002
Charles Barkley hosted SNL on January 9, 2010 (also on September 25, 1993)
Britney Spears hosted SNL on May 13, 2000
Luckily, these hosts had an amazing cast to back them up and pull them through the show. And hosts are only in a couple of sketches and usually have side parts so they didn't entirely ruin the show. These people have not been invited back for good reasons.
