Characters
If you hurt her, I will beat you to death with a shovel. A vague disclaimer is nobody's friend. Have fun!

Our reading
An editorial interpretation.
The speaker delivers a blunt, violent threat: hurting "her" will be answered by a beating to death with a shovel. They then wryly note that a vague warning is useless, and close with a cheerful "Have fun!" The brightness of the send-off sharpens the menace instead of softening it.
