Text widget with no title

Has anyone come up with a text widget with no title – or is there an easy way to strip off the title and the space that is reserved for it. I use the text block widgets to add advertising (mostly adsense) and I don’t need the title – these are display ads and it is obvious that they are advertising. If there were a “text only” widget it would be perfect – I could just add ads in the block without worrying about the title. Has this issue come up here before? – I couldn’t find much.

Thanks
