In south Wales last Sunday, 400 people SKINNY DIPPED together in the sea off Rhossili Beach.

And as a chubby chaser, I'm BEYOND disappointed I missed it... because looking at the photos, the dipping may've been skinny but the dippers were certainly NOT!

The previous world record for group skinny dipping was 250 people, so once the Guinness World Records officials get a chance to review the tapes and photos, the people in Wales should coast to the record.

The event raised more than $8,000 for the Marie Curie Cancer Care charity.
