Dad's Birthday

My dad's birthday is coming up in like 4 days and I don't know what to do for him except bake a carrot cake like every single year. My mom had this idea of us buying him dinner, because my bro n sis saved up a lot of money and they can totally afford it. I can't chip in because I don't save. lol. I usually buy stuff I need like food, drinks, water, bus fares... I don't work either, which sucks, 'cuz dad won't let me. So basically, I can't chip in any money at all. Anyway, I want to do something for him. It really does suck that we as his kids can't do much for him. I feel bad. =( So right now, my brain is like thinking, what can we do for him?
