Jael.

The other week I was reading the book of Judges to keep up my Hebrew, and I was on the story of Jael, who hid a fleeing general in her tent, lulled him to sleep, and then drove a tent peg through his head.

A colleague's wife has that name, so I texted her and told her I was reading the story of her (scary) namesake.

She replied -

Now you know why noone wants to go camping with me!
