Biggest fan rejection to a heel turn?

Have you ever seen a bigger fan rejection of turning someone heel and trying to get them booed like Becky Lynch?  The only one that I think of that even comes close was the Undertaker in late 2001, early 2002.  

Road Warriors in 88. One if the most ridiculously misguided attempts at turning someone ever.  Fans were literally cheering them DURING the heel turn.
