Baseball Party Food Ideas

What’s a good theme for a surprise birthday party?
My friend is turning 29 soon and I want to throw him a surprise birthday party. He likes comics, NASCAR, and baseball, plus he’s gay. Do you have any ideas for a good theme? How should I decorate? What should I do for food? How about invitations?
Do a luau. It’s fun and easy. Plus it’s great for summer time.
Decorations- It’s really easy. Pretty much anything tropical. Grass Skirts, sea shells, leis, tiki torches, etc. Walmart has a great luau party aisle it has every from Coconut bras down to invitations.
Food- Anything you can cook out on a grill. (hot dogs, hamburgers etc.) Drinks you can do pina coladas with umbrellas
Games- Limbo, Conga, Hula dancing
You can come up with great ideas. Have fun with it.
