Stuart Beavon's hat-trick was the perfect birthday present for boss Gary Waddock as Wycombe downed Bury.
Beavon turned sharply to fire the Chairboys ahead, only for Shaun Harrad to head home Giles Coke's cross to restore parity.
Paul Hayes smashed the visitors back into the lead, while Coke's penalty hit the post after Grant Basey had brought down Mark Hughes.
Beavon then bagged a deflected effort and a stunning volley to wrap it up.
VIEWS FROM THE DRESSING ROOM
Bury assistant manager Peter Shirtliff told BBC Radio Manchester:
"You probably wouldn't have seen that coming 10 minutes after half-time.
"It's all about goals and we've let four in, only scored one at the other end, but they've been four pretty cheap goals.
"We'd not be doing our jobs if we weren't concerned, the players realise we've got to get out of this rut.
"Whether we're in a relegation scrap I don't know, all I'm interested in is accumulating as many points as we can."
