A customer at a hotel resort goes to complain to the manager. ""Manager,"" he says, ""there are far too many mosquitoes here. Is there perhaps something you can do to fix it?"" The manager replies: ""Absolutely sir, when the mosquitoes get particularly bad we use my grandfather. We bring him out on his wheelchair and cover him in honey and all the mosquitoes flock to him so that the rest of us can enjoy a nice mosquito-free evening."" The incredulous customer says: ""Why, that's absolutely barbaric! The old man must scratch himself to death!"" The manager replies: ""Oh, not at all sir. On the contrary... he's paralyzed.""
