Hip Hip Hooray! It's a Boy's Birthday Today! It is fun and exciting to plan a birthday party for a boy. Gather together items associated with a theme that you know the lad will love, such as pirate paper plates, Avenger streamers, or a wrestling inspired tablecloth. Add a cake topper that represents the theme of your choice to the frosting filled baked good. At the end of the party, hand out goodie bags to your guests as a way to end a perfect day.
