Yes... come to the looner side! It's pretty bangin', and everyone gives great blowjobs!

In all seriousness, though, balloon blowing exercises could actually help you with the rap thing. Those exercises increase your lung capacity and can help you develop better control of your breathing. Both those things can help you make and maintain a more complex flow to your lyrics.
Of course, there are other methods to increase lung capacity and breath control, but balloons are cheaper.
