I agree with Dan, Wiger and Frapp - the best present is a heartfelt message in a card or verbally.
A lot of guys are like me, if I want something, I get it, so present buying is hard. Unless you can afford that new truck or boat (and if so can I be your second dad?). But I am sure your dad will appreciate anything you get.
My kids always used to but me outrageous ties or cufflinks - and I still wear them. I may not be batman....but I have the cufflinks and tie lol....
