Hide default title tooltip?

I'm using this jquery plugin I recently found, and I'm having some trouble with it. Actually I got it to work quite nicely, the thing is that (as you may notice in that same demo) it works using the Title attribute so when you hover for a couple of seconds over a menu button, that awful default tooltip appears.

I did some research but I couldn't find any simple way to hide those. Any suggestions?

Thanks :)
