Give the guard a drink of water. You can get one from the vending machine in the Pokemon Mart in Celadon City. The vending machine is on the top floor. Once you buy one from it, walk past him and he'll ask you if he can have your drink. Say yes and you will be able to pass.
Get the flute
If you mean the guard by the elavator, you can't get passed him.
You'll need the GameShark now, but there was an past event for Mew being in Pokemon Yellow. It was the Nintendo Rep.
You Can't
Any Pokemon that existed in Red, Blue, or Yellow.
You need to get around to Celadon (via Lavender Town), visit the Pokemon Mansion there and an old lady will give you a hot drink, take it to the guard and he will pass it round.
Don't you mean yellow not lighting yellow? Anyways you get charmander past Nugget Bridge and off to the left and a guy gives you it.
first you go to the town to the right where the grass gyme is and ask the old lady in one of the buildings near the pokemon center then she will give you tea and you take the tea to the guard
In the Pokemon League in Yellow, the strongest Pokemon Lance has is a Dragonite. When you get past him, still there's Gary that finished the league before you do. His stongest Pokemon is Jolteon, an evolve of Eevee. It is level 64 and it is really strong.
