Sometimes

In the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) sometimes Black's Knights can't help themselves, they just have to harass the enemy Queen. It seems like a good idea at the time, but things do not always turn out as they are planned. The time invested in the horsing around is lost.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Kf8 8.Qxc5+ Qe7 9.Qe3 d6 

10.f4 Nf6 11.Nc3  Ng4 12.Qf3 c6 13.f5 N6e5 14.Qg3 h5 

15.d4 Nc4 16.0-0 Kg8 17.b3 Nb6 18.h3 Nf6 19.Bg5 Qf8 

Breaking the pin, while still protecting the (retreated) Knight.

The "Jerome pawns" are getting ready to roll.

20.Bxf6 Qxf6 21.e5 dxe5 

Rybka suggests that the only way out of this mess for Black is tactical: 21...h4 22.Qe3 Qe7 23.f6 gxf6 24.Rxf6 Rh7 25.Rxd6 Bf5 26.Rf6 Bxc2 27.Qd2 Nd7 when White sacrifices the exchange 28.Raf1 Nxf6 29.exf6 Qd7 30.Qxc2 for an edge.

22.dxe5 h4 23.Qf4 Qh6 24.Qd4 Kh7

As in many successful Jerome Gambit games, it is hard not to notice Black's misplaced Knight on b6, and his undeveloped Bishop and Rooks.

25.Qe4 

White had the threatening 25.Rf4, but he had to see that after the tricky response 15...Rd8, he could still proceed with 16.Qe4.

25...Bd7 26.e6 Be8 27.Rf4 Kg8 

28.Qe5 

Allowing the blockade, while 28.f6 was playable right away. 

28...Qf6 29.Qe3 Rd8 30.Raf1 Rh5 

Rybka sees a way out for Black: 30...Nd5 31.Nxd5 Rxd5 32.Qxa7 Rh5 33.Qxb7 Rhxf5 34.Rxf5 Rxf5 35.Rxf5 Qxf5 36.Qe7 Bg6 37.Qd8+ Qf8 38.Qxh4 Qc5+ 39.Kh1 Qxc2 40.Qd8+ Kh7 41.Qh4+ Kg8 42.Qd8+ Kh7 43.Qh4+ Kg8 44.Qd8+ Kh7 45.Qh4+ Kg8 draw

31.Ne4 Qd4 32.Qxd4 Rxd4 33.f6 

Even without Queens on the board, the breakthrough wins.

33...Rxe4 34.f7+ Bxf7 35.exf7+ Kf8 36.Rxe4 Black resigned
