Tottenham tonk woeful Wigan 9-1
Defoe stunned the hapless visitors and equalled the league's single match scoring record with a mesmerising second-half blitz at White Hart Lane after Spurs had gone in 1-0 up at the break thanks to a ninth-minute Peter Crouch header.
After hitting the bar in the 34th minute, Defoe opened his account in the 51st and completed his quickfire hat-trick seven minutes later - the fastest since Robbie Fowler's three in four minutes for Liverpool against Arsenal in 1994.
He netted again in the 69th and added a fifth with a right-foot shot three minutes from time as Tottenham fans sang "we want 10."
Aaron Lennon also struck in the 64th while shell-shocked Wigan keeper Chris Kirkland added to the goal tally in the 88th when a David Bentley shot rebounded off the angle, hit him on the back and went in.
Croatia's Niko Kranjcar scored in the dying seconds to wrap up Tottenham's biggest win for 32 years, when they beat Bristol Rovers 9-0 in the second division, and their biggest in the Premier League.
"The lads can't believe it," said Defoe. "If you look at the finishing, all the goals were unbelievable. I looked over at the manager and he looked shocked as well.
"It's like a dream, it's brilliant." CONTROVERSIAL GOAL
Wigan's only reply was a controversial Paul Scharner goal in the 57th minute, with the player appearing to control the ball with his hand before scoring.
"The result is not normal. It's one of those freak games," said Wigan manager Roberto Martinez. "It was too easy for them to score their first three goals.
"I'm not bothered about the final scoreline. I'm more bothered about how naive we were in one-on-one situations.
"Of course it was a very good day for Tottenham. Their finishing was very clinical and every time they had a shot on goal they scored. But we were very, very naive for the first three goals."

Defeat left Wanderers third from bottom.
David Dunn netted the opener in the 32nd minute, curling the ball into the top corner past the outstretched Jussi Jaaskelainen in goal. Bolton defender Sam Ricketts then headed into his own net in the 73rd.
"Maybe he (Allardyce) should stay away a little bit more," Dunn told Sky Sports Television.
