LMAO Tonya!!
Ok here's some I thought of (most from experience)


Things CAN and WILL explode in the microwave.

Don't try to get the cat to ride on the dog's back; you will have one very scratched up dog and one pi$$ed cat.

Don't try to "dance in the rain" on a plastic picnic table, it will break.

When someone uses the expresion "grab the bull by the horns" they don't mean it literally.
