Why was the math book sad?

Because it had too many problems.

I told my wife she was drawing her eyebrows too high. She looked surprised.

I've been trying to organize my spice rack...

It's taking a lot of my thyme.

I was trying to get my kids to eat more vegetables, so I took them to the garden to show them where they come from.

Now they're rooted in their refusal to eat them.
