What Is A Funny Verse That I Can Put In My Grandfathers Fathers Day Card?

I can't think of a funny verse, but can tell you that in your grandfathers day, many dads would tell their children that they had to walk 5 miles to and from school  up hill, (both ways) in the snow with holes in theirs shoes.
  You could write that you had to walk 5 miles to the store and back, up hill both ways in the snow with holes in the soles of both of your shoes to get him this Fathers Day card.
That might get a laugh out of him.
Or if you live in a hot climate, you could tell him you blew out both of your flip flops and had a flat tire on your tricycle while peddling 10 miles in both directions. When you got to the store, you were a nickle short and had to beg on the street with a tin can to raise the money  to get his card.
He'd most likely appreciate the humor in something like that.
