An engineer accidentally ends up in hell instead of heaven

An engineer dies and goes to hell. He's hot and miserable, so he decides to take action. The A/C has been busted for a long time, so he fixes it. Things cool down quickly. The moving walkway motor jammed, so he unjammed it. People can get from one spot to another more easily. The TV was grainy and unclear, so he fixed the connection to the satellite dish and now they get hundreds of high definition channels. One day, God decides to look down on hell to see how his grand design is working out and notices that everyone is happy and enjoying umbrella drinks. He asks the devil what is going on? The devil replies, "Things are great down here since you sent us that engineer." "What?? An engineer? I didn't send you one of those, that must have been a mistake. Send him back up right this minute!" The Devil responds, "No way. We are going to keep our engineer. We like this guy!" God demands, "If you don't send him to me immediately, I'll sue!" The devil laughs. "Where are YOU going to get a lawyer?"
