Help me to buy a gift to my father!?

how about a homemade birthday card. fold a piece of paper in half, draw a smiley face and when you sign it write names of celebrities, movie stars, sports stars, old friends, neighbors, people from his favorite shows, when you do this 100 names would be awesome. the card will look like when they p it around at work i do these all the time and they go over really well. remember it's the thought that counts and he'll be impressed with the effort you put into it. have fun and tell him i said happy birthday. =)
