Cold Play

So I'm in a bit of trouble.

I spent all of Sunday thinking I'd forgotten something important, but I couldn't remember what. Until I got a text from my best friend a few days later saying "Missed anyone's birthday recently?"

I rang him to talk - I felt terrible. He put me in my place and gloated a bit, but I think I'm forgiven so everything's not lost.

I want to get him something nice anyway. And that's the hardest part - I can't think of anything cool but not entirely useless.

Any thoughts?
I've seen some really funky clocks...
