Claudio Ranieri won the fifth consecutive Goodison Park race at Watford, but it was the Hornets' first win in their entire history.
Claudio Ranieri's return to the Premier League has been a memorable one.
After Xisco Munoz was fired, Watford lured the popular Italian to England. However, his reign began to unravel when Liverpool beat him 5-0 in his first match.
With 10 minutes left, it looked as though they were going to lose two out of two.
The Hornets' astonishing response with four goals in twelve minutes to win 5-2, which included a hat trick by Joshua King, shows that the 70-year old's most recent top-flight adventure may be very, very entertaining.
"The Ranieri factor"
Ranieri's reaction to Everton taking a 2-1 lead through a diving header by ex-Hornets striker Richarlison was to bring in Emmanuel Dennis as well as Joao Pedro.
The dramatic finale was dominated by the attacking couple. Dennis provided two assists, before Pedro coolly scored his fifth.
Instead of sitting back and hoping to score a point following Juraj Kucka’s head equaliser, Watford were encouraged by Goodison Park to win an unlikely victory - their first at Goodison Park in their history.
James McFadden, a former Everton forward, said that "that's the Ranieri fact" on BBC Radio 5 Live. People looked at the results last week and wondered "what can he possibly do?" Today it is.

"They went behind and could have folded but didn't. It was Everton that folded actually. Although it was terrible defending, Claudio Ranieri's and Watford deserve credit. They came back in and took full control of the game, which was a great feat.
King, who was not able to score this season with Everton, said that "Even Richarlison scored, I felt we would get something from this game." The team's belief grew when we scored the header.
"This group is great with its togetherness. This is a team sport, and while I may not score every time, I do sometimes. Just in time for his second game, the manager was in and it was a great performance by the team.
Ranieri was faced with a daunting task: to instill belief in his players after Liverpool's defeat - and he did this by using the week's exciting European action.
"I spoke to my heart and told them that it was possible. After Atletico Madrid's defeat to Liverpool 3-2 in the Champions League on Tuesday, I spoke to my players and stated that Atletico Madrid was one of the top teams [defensively] in the world so if they can concede three goals to Liverpool, Watford could concede five.

"But after that we have to fight every duel for every ball, and I'm very,very pleased with our performance."
Everton frustrates
The home crowd was frustrated by Everton's second defeat in a row, which was their second on home soil. Although there were boos as Anthony Gordon was replaced with Richarlison in the home crowd, it paid off when Richarlison scored within three minutes.
BBC's Eilidh Barour thought there might be something...
Rafael Benitez said, "I understand the frustrations of the fans." "We must show more character and personality in every game. It is important to be able to handle difficult situations.
Demarai Gray, the winger, has work to do for the Toffees in order to prevent these defeats from becoming a slump.
"As a group, we must take responsibility. This is unacceptable. It is unacceptable. It is important to focus and do the right thing.
"It hurts, but we must move forward."
