Can't You Read?G 20

This is another very easy achievement that can be gained on the first level (though it could theoretically be attained on any level really). Almost directly in front of where you start on the first level of the first world, you will find a wooden sign which indicates danger. Simply fall off the world next to this sign to unlock this achievement. It should be noted this achievement has been recognized as being somewhat laggy or bugged, so you may have to do it a number of times before it unlocks, but it will eventually pop.
