A question about Pool (Billirds).

[deacsoft]

The following recently happened in a game of pool at a bar. Two of my friends were playing a game of 8-ball. I was not there.

Friend 1 was down to his 8-ball only. He had no shot and just hit the Q-ball "where ever". Friend 2 says the game is over and tells friend 1 since he didn't hit the 8-ball he loses.

The Q-ball was still on the table. The 8-ball was also still on the table (as well as some of friend 2's balls). What's the call here?

1) Game over. Friend 2 wins.
2) Friend 1 committed a "table scratch" and friend 2 gets "ball in hand".
3) Game continues as normal. Friend 2's shot.
4) Other. (Please explain)
