Money access
Get the remote, and press [C]. Butt-Head will say "Change it". Go to Burgerworld. Go over to the dumpster. Beware of the guy spraying oil and the rats at the dumpster. Grab the dead rat. Then, run to the door to your left. To use the employee-only entrance to Burgerworld, type "28884323" as a password. Pick up the french fries on the counter. Press [C] when you are near the boiling water to place them in. Then, put the dead rat into the water. A pouch will appear which you can sell to the customer. After taking the pouch, go to the right and give the food to the man. After a funny animation sequence, he will give you money. Go outside and re-enter using the customer entrance to see GWAR tickets. Now, you should have money, a password, and GWAR tickets.
More lives
Go to Burgerworld. Go all the way behind the store on both sides, practically against the wall. You should find hotdogs for more life.
Go to the far right side at the dumpster in Burgerworld, where the green hamburger is located. Every few seconds, Beavis will say, "We're sick". Go to the hospital and enter the room marked "Keep Out". All life should be restored.
Fishing rod
To use the fishing rod, go near the couch in the living room. Make sure some kind of food is selected in the menu (for example, pizza or gum). Quickly press [C] repeatedly to get the red ball to the top of the rod. Then, something will come in through the window:
Donut: Policeman
Boot: Earl
Pizza: Cat
Gum: Unknown
When doing the fishing pole part in the living room, do not use the boot. Earl will come in and attack you, causing the loss of a life.
Remembering the password to Burgerworld
If you look at the letters on the numbers, the password spells out "BUTTHEAD".
Glitch: Strange graphics
Enable the "Two player items" code. Press [Start] and go to the box where it shows items that you have picked up (Pizza, Headphones, GWAR ticket pieces, etc.). Press [Down] and your graphics will glitch.
Glitch: Go to the Gwar concert with incomplete tickets
