Gift For My Best Guy Friend?

So one of my guy friends birthday is coming up on the 26th (I'm a girl just btw lol) so I have a whole but I don't want to procrastinate on it. Basically there's a pretty big problem; I can't spend money. It's a complicated reason why but yeah I just can't.

My other girl friend (it's like a group of three/four-mainly me and my friend Ash and him) my other girl fried Ash is just drawing him a cute little picture because she's flipping amazing with a pencil and paper. I,on the other hand, only have the ability to write exceptional stories.

Im pretty stuck on what to get him so yeah.

If it helps he's :

More on the slightly nerdy side. He likes to read but he hate schoolwork so he just gets it done as quick as he can. He's really funny and a total sarcasm freak. We laugh alot when we're together and even though we haven't known each other more than a month, we consider ourselves as like best friends.

I don't know if I should just make a friendship bracelet or WHAT . Please suggest FREE gifts I could make/find around the house.
