Here is a 1/0 bullet game:
POST MINIATURES 10 MOVES OR LESS
@freaky25, since he meant 5...Qxd1+ probably, this shouldn't be considered a miniature win. Mouse slip occours sometimes.
The final of the 2012 Micronational Chess Championship (the chess championship for micronations) was decided pretty quickly when Kuri Kabanov of Renasia blundered a queen on the 6th move against Amin Jafarov (also of Renasia).
The game where the player kept moving his king was not prearranged. I would not put a prearranged game in this forum. It was the only game like that in hundreds of my 15 minute games.
I just put it here because it was unique and to some it is funny and to some it is not. [to me it was funny]
After that whole "Bobby Fischer" thing on ICC about the guy who used a computer against Nigel Short, people started playing 1.f3, 2.Kf2, 3.Ke3 occasionally, which resulted in this miniature:
I've witnessed this game occur in a club tournament (it was the board next to mine). The guy playing Black reached out to move the knight on b8, but accidentally brushed his king with his shirt sleeve. White called over the tournament director, who enforced the touch move rule, and you know the rest. 
Just now, although not completely mate. He totally fell for the Queensgambit and blundered..
It is forced mate in ten moves after 8. Qxf7+ Kd7 9. Qf5+ e6 (9... Kd8 10. Bf7#)(9... Kd6 10. Qe6#) Qxe6#
