how warm is luke??

following a conversation with greg, andy and his dad about the difference in temperature between my tap water and the cooper's the question arose.. how warm is luke?? how i hear you ask as you scratch your befuddled bonses.. well bryan stated that his water was luke warm,.. a common pharse we all accept without thinking..however how warm is luke so that we actuially know what we are gaging when we say something is luke warm.. and why not john or greg or cathy even? we need to know how warm luke is so we can be assured we are being accurate when we say it is luke warm, after all we don't want to be saying things are luke warm when actually they are only john warm! people i hope you are all as concerned as me! so what i propose is we measure the temperature of Luke when he is cold, neutral and warm over a period of weeks (scientific this!) until we settle on the average luke warm temperature.. so then we can say when something is luke warm and know we're right! what ya think?
