Kidding aside, if it's been on a longer while than intended to be, it may have dried onto the lens. Just take some rubbing alcohol to it on cotton (like a Q-tip or cotton ball). That type of alcohol is used by techs to clean electronic parts, etc, as it evaporates quickly and leaves no residue.
A clean small piece of wooden article, such as the mentioned tooth pick will work, as will a pencil eraser.
But the sledge.. now that could be fun. Expensive, but fun.
