Replying to Condom/birth control RAP.

yo so i have to do some kind of presentation for health class on condoms which are my topic. we can do it via video, skit, poster, ppt, or song. you get the picture, anything we want to do.  my friend and I are thinking of doing a little collab between the condom and 'the pill' and making 1 rap.  it needs to cover the ups and downs, dangers,  basically an all around knowledge of each for the class.

any ideas to start out a rap?!
