Jamie Vardy and Harvey Barnes each scored twice as Roy Hodgson's final home match in charge of relegated Watford ended in an embarrassing 5-1 loss to Leicester.
Joao Pedro's deflected effort gave the Hornets an early lead in front of incoming head coach Rob Edwards, who led Forest Green to the League Two title this term, and received a ripple of applause as he was unveiled to a sparsely-populated stadium ahead of kick-off.
But familiar defensive issues contributed to the hosts' downfall as James Maddison's leveller and doubles from Vardy and Barnes condemned them to a 26th Premier League loss of a miserable campaign.
The Foxes' victory was relatively straightforward after their ongoing set-piece frailties were exposed early on and keeps them on course for a fifth-successive top-half finish.
Meanwhile, Watford's latest defeat equals the overall top-flight record of 15 home reverses in a season and leaves former Forest Rovers boss Edwards in little doubt about the major summer overhaul required.
Veteran former England manager Hodgson, who turns 75 in August, will depart the Hornets having failed to taste victory on home soil and with just next weekend's trip to Chelsea to improve a paltry return of nine points from 51 available since his January appointment.
Substitute Jeffrey Schlupp netted a late equaliser as Crystal Palace secured a 1-1 draw at fellow mid-table side Aston Villa.
Schlupp finished from close range in the 82nd minute to cancel out Ollie Watkins' 69th-minute opener.
Lucas Digne had a strike saved by Jack Butland and Watkins hit a shot wide in stoppage time as a subsequent Villa push to reclaim the lead proved in vain.
The result left Patrick Vieira's Palace and Steven Gerrard's Villa still in 11th and 12th place respectively, a point apart.
Rayan Ait-Nouri's first goal in 19 months salvaged a point for Wolves against relegated Norwich.
The defender struck to rescue a 1-1 draw at Molineux after Teemu Pukki's 11th goal of the season gave the Canaries a first-half lead.
Eighth-placed Wolves extended their winless run to six - a streak which officially ended their hopes of a return to the Europa League.
Meanwhile, Norwich did at least end a run of five straight defeats but they remain bottom of the Premier League.
