This is probably one of the world's oldest "bits."
This is also the age of being super cheap when it comes to birthday cards.
By reusing this one card, 84 cards were saved.
This is hands down the most "cheap dad" way to save the environment.
I'm sure there is sentimental value to this card, but I bet venusreincarnate's dad feels the same joy when he signs that card as when he yells stuff like, "Close the door, we're not air conditioning the street!"
