Great joke for a bar...

Some time ago, a pregnant woman was waiting in line at the bank when a bank robber comes running in. The robber begins waiving around his gun and yelling at all the tellers frantically to give him the money and get down. A hidden security guard watches as the robber appears to be losing control and is afraid he may shoot people. The security guard realizes he may only have one chance at this, so he takes aim at the robber, and carefully fires, taking him down in one shot. As the robber falls, he gets off three shots, all hitting the pregnant woman in the stomach. She is immediately rushed to the hospital and stays in emergency surgery for a while. As she comes out from being under general anesthesia, there's a doctor standing over her telling her she's going to be alright. The woman then asks the doctor how her baby is going to be? The doctor smiles and tells her, "actually, you're going to have triplets, 2 girls and a boy. They all have a bullet lodged in their body that will pass out through normal metabolism." The woman stays in the hospital for a few more days before returning home. She eventually has 2 girls and a boy and around 12 years later, she is at home in the kitchen doing dishes. One of the girls comes running out of the bathroom with a very worried look on her face. The mother, upon seeing this, stops and asks her daughter what's wrong? The girl says, "mommy, I've done a very odd thing." The mother asks her what she did. The girl says, "I was on the toilet, and I pooped a bullet!" The mother thinks back to her stay in the hospital, comforts the girl, and tells her the whole story. About 2 weeks later, the other daughter comes out into the garden while the mother is working. The daughter has a concerned look on her face and the mother asks her what is wrong. The daughter says, "mom, I've done something very weird." The mother asks her what she did. The girl says, "I was on the toilet, and I pooped a bullet!" The mother remembers this from 2 weeks ago and comfort her daughter while explaining the story. Well, about 4 weeks later, the son is sitting on the couch, rocking back and forth, not sure what to do. The mother sees this as she comes walking in the door after returning from the store. She stops in tracks, looks at her son, and asks him whats wrong. The boy looks at his mother, looks around carefully, and says, "mom, I've just done a horrible thing and I didn't mean to." The mother thinks for a second, and she says, "did you poop a bullet?" The boy looks up at his mother in shame and says, "no, I was masturbating and I shot the dog."
