#7 The Rock: 2003
The Rock took a hiatus from WWE TV in 2002 when he lost the WWE Championship to Brock Lesnar at Summerslam. Rock was booed so much in this match (as a face) that he decided to cancel his farewell for the time being.
The Rock's next WWE appearance was a pre-taped 'via satellite' interview at the 10th Anniversary of RAW special in January 2003. Rock was booed so much during this you would have thought he was a heel. It was so embarrassing, when Rock did one of his trademark catchphrases, such as 'The Millions', the fans didn't respond, but it being pre-taped, Rock reacted as if they did. He was booed during the entire promo, even when ripping on heel stars.
Rock returned to the TV in February for a WrestleMania rematch with Hulk Hogan at No Way Out. Rock was again booed, but this time for the right reasons, he had turned heel the week prior in a segment with Hogan. The boos lasted just about a week as Rock then debuted his 'Hollywood Rock' persona, which was a pure comedy gold.
A mini feud with The Hurricane only brought out his comedic heel chops even more, and Rock was cheered even more. He received a fair reaction during his match with Steve Austin at WrestleMania 19 and was cheered during his feud with new face, Goldberg. He turned face again in June during the first 'Peep Show', with Christian.
