Question:

Name of the artist who made the video I've seen in the Tate Modern?

Hi,
Three or four years ago, while visiting the museum, I've seen the video of a guy boxing himself. a bit strange, but anyway... A few months later, I've seen a complete exhibition in Oslo (not 100% sure this was the same guy, but almost), a bit tough, with some scatology, and a video where the guy is dressed like a clown and makes a parody of a cooking TV show. Does anybody know who I'm talking about?

Best Answer - Chosen by Asker:

The artist you're looking for is called Paul McCarthy - an American artist, creates installation performances (which he records and shows as videos) he's a very famous contemporary artist, you should have no problem finding stuff about him - just google him.
