Which one's Shakespeare? Who can say? Above we can see (from left) the Cobbe Portrait (1610), the Chandos Portrait (early 1600s) and the Droeshout Portrait (1622). They are all supposed to be portraits of Shakespeare, and you can see the many different portrait versions on the wikipedia page or at Pictures of William Shakespeare.
When not tipsy, I am firmly in the 'I don't care who wrote Shakespeare' camp. As I'm not tipsy at present, all I'll say is that I like Sonnet 94 very much:
They that have power to hurt and will do none,
That do not do the thing they most do show,
Who, moving others, are themselves as stone,
Unmoved, cold, and to temptation slow;
They rightly do inherit heaven's graces
And husband nature's riches from expense;
They are the lords and owners of their faces,
Others but stewards of their excellence.
The summer's flower is to the summer sweet,
Though to itself it only live and die;
But if that flower with base infection meet,
The basest weed outbraves his dignity:
For sweetest things turn sourest by their deeds;
Lilies that fester smell far worse than weeds.
