DH did a lot of gardening after we bought our house a few years ago, and a week or so later complained of a sore bit on his scalp.
Lo and behold; a magnificent spot, red with yellow edges, raised and ready to go.
I got a hot flannel, sat him on a kitchen chair, and applied the cloth.
A finger either side, and crack! - a plume of pus shot out, leaving something spiky about a millimetre long poking from his noggin.
Ignoring all protestations, I grabbed the bugger with tweezers, and gently teased it from his head.
It was only a tiny bit of branch, but as it left his skin it came out with a wonderfully thick green liquid, and left a perfectly circular hole.
T'was a truly wonderful day.
