Blame
The life of a shellfish is filled with blame. They take the blame for everything from food poisoning and allergies, to cutting people's feet on beaches.
Just imagine an innocent little shellfish, living its quiet little life, while everyone's heaping blame on it. It hides in its little shell and tries to deflect all that blame. What a life!

When those poor shellfish aren't having blame piled on them, they're being eaten, because shellfish are thought to make for a very sexy (せき) meal.
Imagine trying to look sexy as you slurp up those saucy little shellfish.
