Chip-off, heh. That reminds me of the 2000 Met Amateur (conducted by the MGA, another fine golf association). We were playing off for medalist and after three holes of a playoff (one, two, and nine East at Ridgewood CC) all three of us had made pars. The sun was getting low and they asked us whether we wanted to continue or have, say, a chip-off. Everyone was tired after playing 39 holes already and wanted to get in, but I was in shock, and said, "Sorry, but this isn't the Merrill-Lynch Shootout, I think we should keep playing" (It didn't help that I had just missed a short one for birdie).
So, on we went and all of us made pars on one and two again. Before we teed of on nine the official said we would have no more sunlight after this hole (it was already pushing it) and have to do a chip-off if it wasn't decided at that point. Luckily for me, I ended up holing a seven iron approach shot for a two to win the playoff. It was so dark we couldn't see the ball go in, but we did hear a shout or two and the official up by the green sent word over the radio. Let's just say I'm glad we didn't make it to the chip-off ...
