Men's Birthday Cakes

I was asked to do a man's birthday cake from someone I only know casually. Her son was coming for a visit from out of state and it happened to be his birthday. The only details that she wanted was for it to be a 10" round chocolate cake. Okay...can do. "Do you want certain decorations or colors?" "Oh whatever you do is fine." Aaaaagggghhhh! I like a little bit of an idea or my mind runs rampid!!! There are too many things for me to choose from!!! But this is what I came up with.
