What just happened?

So I was just playing the computer on here and it played a move I've never seen before where their queen jumped my knight and took out my queen.  Is this some move I've never seen before?

 1. e4 d6 2. d4 Nf6 3. f3 Nc6 4. g4 Nxe4 5. fxe4 Bxg4 6. Qxg4 Nxd4 7. Be3 Nxc2+ 8. Kd2 Nxa1 9. Kc3 e5 10. Nd2 d5 11. Qd1 d4+ 12. Kd3 dxe3+ 13. Kxe3 Qd4+ 14. Kf3 Qxb2 15. Nc4 Qd4 16. Nd2 Be7 17. Bb5+ Qxd1+

Yes, I'm a noob.

As you say, it's not possible.  I played through your moves, and you clearly have a Knight on d2 after 17.Bb5+ .  However, if this is really moves by a computer, a bigger concern is why is it ignoring the check of the Black king by the Bishop?  If the Black Queen is moved, any move except 17...Qd7 does not resolve the check condition.

thanks for the reply.  At least I'm not crazy
