I'll just go with his Shamrock feud as thats one of all time favourites. Shamrock taps him out at SS, Rocks still the chicken heel but is pretending hes hardcore (which is great as he didnt even win the belt in the ring). At the Rumble Rock pulls the brass nucks finish and slips them into Kennys trunks for a genius heel move. Kenny then predicably goes batsh1t.
In the build up the mania Kenny smashes through the Nation until Rock gives him the single most vicious chair shot ever to the face. The Mania match while short is amazingly booked, Rock taps like a biatch, but keeps the belt as Kenny goes batsh1t again after murdering Karma Henry & D'lo.It even plays into the Farooq fued with Rock with Farooq watching on as he has a few times while Kenny has Rock in the ankle lock.
Forward to King of the Ring and Kenny finally gets the win tapping out Rock. You can argue it even goes onto the best 3 way cage match at Breakdown where Mankind/Rock & Kenny have a cracker.
I love this feud, the way Rock sneaks out as champ even when Kenny has blitzed him to pieces, where the underlings are constantly doing everything to save the belt, the dissention in the Nation with Farooq, adding in Mankind at the end and even, as terrible TERRIBLE as it is HHH on commentary for the KORT leads off to him and Rock at SS.Great booking, Everyone came out looking strong. Rock is great. Kenny is massively underatted as a scary lunatic. D'lo/Karma/Henry are great as the minions and Farooq is ace as a guy knowing hes about to get usurped but is still laying down the law.
Love all of it.
