After all, it’s the thought that counts.

It wouldn’t be Mothers’ Day without a heartfelt card, would it?

With empty pockets and plenty of free time, often kids are the best at this bit. And let’s face it, children really do have a wonderful way with words.

At least we like to think so.

In fact, we could think of anything more appropriate for a Mothers’ Day card than insults, laundry demands and references to the male anatomy.

Here are the BEST worst Mothers’ Day cards we’ve found. In all their innocent glory…

4. Talk about all-consuming love.
