Bob works in a saw mill. One day he comes into work, and his friend Ted asks him, ""Hey, did you hear about Joe?"" ""No, what's up?"" ""Well, he was working late last night and cut off his hand."" ""Holy crap Ted, is he alright?"" ""Oh yeah, we picked it up, put it in a ziplock bag, and he got it sewed back on. He'll be back in a week."" ""That's good, give him my best."" A couple days later, Ted asks Bob ""Hey, did you hear about Paul?"" ""Yeah, I heard he got hurt. What happened?"" ""He ended up cutting off his foot!"" ""Wow, is he alright?"" ""Yeah, we scooped it up in a ziplock bag, and he had it reattached at the hospital. He'll be back in a week."" ""That's great, modern medicine sure is awesome."" A few days later, Ted comes up to Bob again and asks, ""Hey, did you hear about Bill?"" ""Oh dear, what happened this time?"" ""Well, he cut off his head last night."" ""Holy crap! But he's alright, right? Scooped his head up in a ziplock bag and had it reattached at the hospital?"" ""No Bob, he's dead."" ""Wow, how come?"" ""Well, we're not sure, but we think he suffocated in the bag on the way to the hospital.""
