Two lads in their local, see a newbie at the bar and decide to talk to him. The guy is well dressed, and looks like he's doing ok for himself.
"what do you do mate? Not seen you in here before"
"i'm a logical scientist", says the man.
"What does that mean"?
The guy replies, " that mean's I can tell you things about yourself, just by asking you questions, and applying logic"
"i'll show you, Do you like fish"?
"yeah", said the local, "I've got a few in the garden"
"So, if you've got fish, you must have a garden big enough for a pond"
"yeah, quite big" said the man
"so, you must have quite a big house"?
"yeah, i've got a 5 bed detatched"
"so if you've got a big house, you must have a large family"?
"If you have 4 or 5 kids, you must have a pretty wife"?
"yeah, she's lovely", he says
"so if you have a beautiful wife, I bet you have a pretty good sex life"?
"if you have a good sex life, chances are, you don't need to masterbate?
"no, no, I dont need to do that kind of think"
"Well" said the chap, "that gives you some idea of what I do"
"thanks mate, very interesting". With that, he goes and sits down with his mate.
"what did he say", said his mate
"well, said the first guy, I think I can tell you things, just by asking you questions"
I'll show you. "do you like fish?"
"No", said the friend.
"ah, said the first guy, you must be a wanker"!!
