This is commitment to a cause

From the Guardian (kinda NSFW):

If the certainty of having your collar felt, metaphorically of course, by the local police every few days is not enough to put you off walking the length of Britain naked, then the February wind blowing off the Pentland Firth should at least be a deterrent. So, as the Naked Rambler and his girlfriend finally arrived at the northernmost tip of Scotland yesterday, their first thoughts turned to clothes.

"Quick, get them on," said Stephen Gough to his partner, Melanie Roberts. It is a phrase that has been muttered, without success, by a good many people since the pair set out in their birthday suits from Land's End last June. The lady in the shop in Shropshire where they stopped to buy piccalilli said it. The kirk minister affronted at their flesh said it. The local magistrates said it. The prison governor said it. But where man failed, only nature could prevail.
