HELP! tomorrow is FH's bday and....

I spent a ton of $$ on him for xmas, so he said not to spend more than $10 on his bday. Any ideas of something really cheap but cute that i could get for him?

Is he into baseball? when i went to sharper image for x-mas shopping they had this laser baseball...basically a baseball you throw and it clocks at how fast you threw it, it has the timer thing on the ball...when the guy had suggested it to me, i was like hmmm no...when i told FH he was soooo disappointed, he was like omg i ALWAYS wanted one of those things...so i went on a search for it, at work when i told the guys they too were like OMG that exists thats the greatest thing...When i came back to work they were like omg did you get the ball, how is it? It was sold out at the city stores...but sharper image at roosevelt field mall has it...hmmm just a though.
