#2 Al Sharpton
WWE has had some unusual celebrity guest hosts over the years, but Reverend Al Sharpton had to be the most out of place.
Sharpton appeared as a guest host in September 2009. He was there to promote Educational Reform in America, and while this was a noble cause, the Rev was just too out of place. He appeared only a few times, most notably in an awkward segment with Chris Jericho, Big Show, MVP, and Mark Henry, where he was booed throughout.
The only other time we saw him for the rest of the night was backstage with Jillian Hall and The Bella Twins, where he gave us a song. It seemed like all WWE did with The Bella's in 2009 was have them accompany the guest hosts everywhere they went on TV.
When talking about WWE RAW Guest Hosts, Chris Jericho cited Al Sharpton as possibly the worst, claiming he showed up after RAW began, left before the show was over, and didn't interact with anyone backstage.
The WWE's guest host setup was generally underwhelming considering how little the celebrities knew about the industry and the storylines that were currently running.
