I'm a baker, and I'm feeling crumby today.

What do you call a sad strawberry?

A blueberry!

So I was at the beach with my kids, and we saw a guy selling shells. He had all sorts of shells, from big conch shells to tiny clam shells. My kid asked him how he managed to collect so many

and he said it was a shell of a job!

Why did the math book look sad?

Because it had too many problems.
