What's The Best Way To Spoil A Surprise Party?

Oh, you need to know why? Fine...
  1. My father's married to a she-devil.
    Her facebook profile photo 👆🏽
  2. She spends money a lot, and makes money... very little.
  3. To keep her from wasting money my father has stopped having parties at his house. They now do informal, "pot luck style" hangouts instead.
  4. Especially for his birthday and Father's Day.
    Plus he is a bit of an introvert and really appreciates alone time. My step sister and her 3 children have moved into his house, so he has had no time alone.
  5. This year, he retired and turns 55. So to get around his "Stop Spending My Money" rule, she wants to plan a surprise 55th/retirement combo party.
  6. We already celebrated his retirement.
    That's us last month. Celebrating his retirement.
  7. She planned a surprise party for his 40th and 50th birthdays, and WAY overspent!
    She rented out an entire restaurant and he got to pay the bill.
  8. Anyways, I'd like him to know it's coming so he can nip it in the bud.
    Edit: She spoiled my surprise party this March, so it is her turn.

  14. Tell him his identity has been stolen and he should cancel all his cards right away and never give it to his wife.

  15. Along the lines of @MaddyandOwensMom can you have a genuine discussion with him? "Hey Dad, so here's what's being planned..." Also, that's a cute pic!

  16. Sheepishly ask him if he didn't like his first retirement celebration. When he says he loved it then be like well your wife is taking your money for another one!

  17. Kidnap wife until she has Stockholm syndrome and agrees to never spend money again.
