I wasn't fooling about the shape of Buzz. Of course, if you happen to get one of the cars with a good gun, you will not notice it. But, I rode it 4 times in a row in March 2002 and 3 times the guns were not working correctly. When you DO happen to get one of the bad guns, you will still get some points because the computer gives you a few points every few shots you make - whether or not the gun is aimed correctly (or at anything at all.) But, if you have one of the bad guns, that is ALL the points you will get. You can tell if you have a bad gun because you will not see the red light as you aim the gun - even at the wall right in front of you. I wrote to Disney about it and they said that the information would be forwarded to the proper person.
Oh, and Zurg, even if you didn't notice the great number of guns being out of order, surely you noticed all the peeling paint on the cars. This is a disgrace to Disney to let a ride run down so much.
