This happened to me when I was a teen. I was happily eating Rice Krispys and then happened to look down to see little worms all over...the exact same size as the Rice Krispys.spew alert....
One evening many many years ago my husband and I were sharing a nice romantic late evening snack in front of the TV set. We were having some rye krisp crackers with butter, salami, herring, a real nice snack tray, just the light from the TV, gazing lovingly into each other's eyes, etc (we probably weren't married yet, LOL).
We ran out of crackers, so I told him I'd go to the kitchen and get some more out of the box.
Everything was all jumbled on the kitchen counter, so I put the light on to get the crackers. I grabbed some out of the box, went to put them on a dish, and saw they were CRAWLING with those little mealybugs. I mean just loaded with them.
I let out a SHRIEK, he came to see what was wrong, we both about vomited. Talk about ruining a romantic mood!
