Larry has his wallet from the beginning of the game on with a little starting cash. He uses it to buy whiskey, pay taxi rides, in the store, to pay for a wedding, and more. The only way for Larry to earn money is to gamble in the hotel's casino, either on the slot machine or by playing Blackjack, which he will have to do on at least 3 occasions. Make sure not to run out of cash completely.
Larry has the breath spray with him from the beginning of the game. Every 10 minutes, the game will politely indicate that Larry has a bad breath. For instance, when a window pops up saying "your mouth tastes like the inside of a motorman's glove", then it's probably time to use the breath spray. It can be used 10 times before it is empty.
Larry has the pocket lint with him from the beginning of the game. It is not used in the game to our knowledge. Perhaps it was part of a puzzle which was cut out of the game.
Larry 1 is actually a timed game. By looking at the watch, which Larry has from the beginning, you can find out the exact time in the game. You may also enable the game clock in the top menu. The game begins at 10pm and uses real-time minutes. Every 10 minutes Larry needs to use the breath spray. Also if, when the sun comes up, Larry is still a virgin, he will shoot himself in the head. This particular death scene was removed in the 1991 Larry 1 remake.
