Father's Day ideas?

Yikes...it's only a few days away, and I've been so focused on ideas & gifts for John from the kids, that I just realized that I have nothing for my own dad! He's the kind of dad that really doesn't want anything. He hates the fact that I spend my money on him, but of course I want to get him something because he's a great dad...one that I want to honor & let him know that he's loved! Honestly, he'd be very happy with some lottery tix, but wondered if anyone else had any different ideas! I'll give you a little insight...he loves football, baseball, grilling, beer, his grandkids....typical dad stuff! :)
