New Super Mario Bros. Tips

Easy 5 lives
Go to 1-1 and go to the part where you get the Mega Mushroom. Don't get it just yet, stand behind it so that it will go forward. Follow it until it's about to go down the hole. If done correctly, you should be able to be Mega Mario/Luigi till the end of the level. Be sure to knock down the stairs and the flagpole. Mario/Luigi should look back then turn into their normal selves (with the mushroom upgrade) and they should go forward into the castle, getting the 5 lives on their way.
