I don't like having to make a meal when I come in from a run so I'll often put a jacket potato in the oven before I go out (HSE OFFICERS WINCE NO DOUBT!).
Mmmh, well I eat the skin if the JP is well-cooked. But so many places serve JP's with skins as tough as cardboard. They hurt my jaws too much. And then I leave the skins alone.
I've also just realised I never cook JP's at home!
