Nonetheless, every now and then I see something that is sufficiently tasteless and offensive that even I'm shocked. When I saw this advert in the Metro today, for example, my future monocle fell right into my lap.

Bleh. I can't be bothered to explain all the things that are wrong with this. Just bear in mind that Two and a Half Men is a show in which Charlie Sheen plays a character called Charlie Harper. He's pictured with lipstick on his face, mud and rips in his shirt, and a halo...
You see what they did there? They've used Charlie Sheen's notoriously violent conduct towards women to promote their show! Oh how very nice.
