Ishmael Miller scored the only goal as Nottingham Forest moved out of the Championship relegation zone with victory at Watford.
The striker shinned the ball past Scott Loach after Watford failed abysmally to deal with Lee Camp's goal-kick.
Watford's best chance to equalise came when John Eustace seemed to shout to Martin Taylor to leave the ball, but then failed to take the chance.
And with three minutes remaining, Eustace fired straight at Camp.
It ended a run of three consecutive defeats for Forest, but Watford have now matched that run with this result.
The visitors shaded a dull opening period, with Clint Hill glancing wide and Joel Lynch going close with a header and then a volley.
But Watford had the best chance of the half, with Camp pulling off a brilliant reflex save from Joe Garner's header.
After the break, Forsyth scuffed his shot against Camp's legs and then headed over minutes later.
Garner headed wide the most glaring chance of the game and was made to pay by Miller's first league goal for his new club.
