Doctor Com walks around. He finds a high power vacuum cleaner, and some fans. he picks them up, and walks to the Ammonia cloud. He looks around, and somehow finds a way to upgrade one of his knives using all the gold in most of the shops. He finds a random guy walking through for a milisecond, gives him a knife and all the gold. He gives him one Subtle Knives, slightly dulled by so much use.
Subtle Knives are made by Subtle Inc. They can cut through anything, and are primitive methods of multiversal travel.
He cuts a hole in the fabric of time and space, and drains out the gas. He walks around a fair bit more, until he hears the explosion. He holds the duct tape and super glue, and gets to rebuilding the destroyed shop. He walks into the car dealership, and grabs a laptop. He places a new car where the old one blew up, and re-paired the shop. He finds a gold cart, and drives around the store, calm. He finds a sign shop, and finds one that says, 'Space Janitor: The movie.' He attaches it to the golf cart.
