Best methods to prevent abortion: 1. A case of Trojans including glow in the dark so you know where things are, 2. No means no, meaning put your thing in something else, 3. Vasectomy, 4. Tubal ligation, 5. In the case of idiots, mandatory sterilization, especially of Congressmen, namely Louie Gohmert, Steve King, Joe Barton, Michele Bachmann, Dana Rohrabacher, Paul Broun, oh hell, the whole lot of them.
Best form of pre-abortion: a good swift kick to the nards with steel toed boots. Guarangoddamnteed to get the job done. I find it very effective. In the case of Rush Limbaugh, you'll have to hire a forensic team to find 'em. Probably why he doesn't have kids as they might have gone back to whence they came.
