The Mysterious Mail Trick
This is just a cool trick that you can try, it doesn't serve any purpose. Load the first game under the player "Easy" (is installed with the game). This should skip you past all the introduction so you don't have to watch it. Once the room loads, ensure disc 2 is not in the drive, instead put in another disc. Now, get the gun. It will ask you to insert disc 2. Instead of doing this, hit "cancel". The gun will be gone, but even stranger is that the surgery gift certificate is now in your inventory! Now for something even weirder! Look at the picture of Sylvia on Tex's desk, but again when the box pops up asking you to insert disc 2, hit "cancel". This time Tex will make a comment about the mail (I won't spoil it for you). Thanks to Blair Yeany for this cool thing to try!
