Kent moved level on points with Warwickshire at the top of Group C in the Clydesdale Bank 40 with a six-wicket triumph at Edgbaston.
The Bears - who had previously lost only once in the competition this year - were skittled for just 92 in 30.4 overs, their third lowest one-day score at their ground.
That in itself was something of a recovery after they had found themselves 15-4 and then 57-8 against a Kent seam attack that made the most of helpful conditions in the day-night fixture.
Darren Stevens finished as the pick of the attack with 4-25, though it was Mark Davies and Azhar Mahmood, who both finished with figures of 2-14, who started the rot with a pair of early wickets apiece.
Simon Cook accounted for Tim Ambrose (10) and Jeetan Patel and when Stevens had Keith Barker caught at second slip, Warwickshire - without England Lions duo Varun Chopra and Chris Woakes and the injured Steffan Piolet - looked in danger of not passing 65, their lowest ever one-day total.
They were at least spared that indignity by Rikki Clarke, the former Surrey all-rounder, actually playing in the game as a batsman only due to a torn abdominal muscle, playing a restrained innings of 35 not out.
Paul Best (15) helped add 27 for the ninth wicket before Stevens - fresh from a five-wicket haul against Derbyshire on Sunday - wrapped up the innings.
Kent may have sensed the chance to complete second 10-wicket hammering of their opponents when Rob Key and Sam Billings put on 26 in five overs.
However, they suffered a wobble when four wickets fell quickly, both openers perishing before Darren Maddy removed Stevens and Sam Northeast cheaply.
Yet any slim hopes Warwickshire may have had disappeared thanks to a fifth-wicket stand of 39 between Azhar (20 not out) and Alex Blake (18no) that guided the visitors over the finishing line with just the 118 balls to spare.
