That Pink Stuff

This recipe recently came my way courtesy of a fruit recipe swap on swap-bot. I made it yesterday and it is yummy.

That Pink Stuff
1 small container cool whip
1 small can sweetened condensed milk
1 large can drained crushed pineapple
1 can cherry pie filling
1 cup chopped pecans
Dump it all in a large bowl and stir until well combined.
Chill at least 7 hours.

I only had chunk pineapple at home, so when I went to the store to get some of the other ingredients I did not have on hand, I knew I wanted to get crushed pineapple. I even saw the crushed pineapple on the shelf. I reached for the crushed pineapple. By the time I unpacked my groceries, it had metamorphosed into chunk pineapple. How does this happen? And it isn't the first time. Oh, maybe with pineapple it is the first time, but how does the cream of mushroom soup I reached for become vegetable beef (also a lovely soup, but not so good in tuna casserole) or the pistachio pudding become butterscotch. How?
Some may say that I am the common denominator and that when it comes to shopping I do not have good eye-hand coordination, but no, I believe it is some sort of early teleportation experiment being conducted by scientists in area 51 trying to reverse-engineer some alien device they have acquired.
I sure hope they work out the bugs soon. This is getting annoying.
Anyway, if you have been subjected to their experiments, just cut up the chunks into smaller pieces.
