On Father's day.
Tell him that it is so much easier for you when he leaves the toilet seat up.
Tell him that yes Nachos are a major part of the new food pyramid.
See if you can find a remote in the shape of a nekked wimmin.
Have the kids where T shirts that say " we have the world's smartest dad"
Suggest installing an indoor putting green.
Where a man's t shirt to bed, bring a pair of scissors and tell him to open his present. If he is a little clumsy you might want to go get a pair of safety scissors.
A sincere Thank you is worth more than anything you can ever buy for him.
