A teenager comes home from school with a writing assignment.  He asks 
 his father for help.  "Dad, can you tell me the difference between 
 potential and reality?"  
   
 His father looks up, thoughtfully, and then says, "I'll display it to 
 you. Go ask your mother if she would sleep with Mel Gibson for a 
 million dollars. Then go ask your sister if she would sleep with Brad 
 Pitt for a million  dollars.  Then come back and tell me what you've 
 learned." 
    
 The kid is puzzled, but he decides to see if he can figure out what 
 his father  means.  He asks his mother, "Mom, if someone gave you a 
 million dollars, would you sleep with Mel Gibson?"    
   
 His mother looks around slyly, and then with a little smile on her 
 face says,  "Don't tell your father, but, yes, I'm sure I would."    
 
 Then he goes to his sister's room and asks her, "Sis, if someone gave 
 you a million dollars, would you sleep with Brad Pitt?"  His sister 
 looks up and  says, "Omigod! DEFINITELY!"  
   
 The kid goes back to his father and says, "Dad, I think I've figured 
 it out.  
   
 "Potentially, we are sitting on two million bucks, but in reality, we 
 are living with a couple of whores."

 Son brought girlfriend back to meet dad.  
 
 Son: "Dad, come meet my girlfriend, I want to marry her". 
 Dad sees girl, pulls son aside : "Er... son, I'm afraid you can't 
 marry  her. I'm sorry, I was once wild, I had some flings - she's your 
 half-sister".
   
 Dejected, son gave up girlfriend. 
  
 Few months later son brought new girlfriend to meet dad. 
 
 Son:"Dad, meet the girl of my dream, the girl I want to marry." 
 Dad meets girl, takes son aside : " Er....son, I'm sorry this no can 
 do  too! She's also your sister" 
  
 (Dad must have been an extremely virile casanova!) 
 Son grew very depressed, goes to mum. 
  
 Son: "Mum, life's unkind! Every girl I want to marry turns out to be  
 dad's daughter from somebody else!". 
 Mum, nonchalantly, : "Don't fret dear, go marry your girlfriend. 
 Don't  worry about dad - he's not your father!"

 A brunette, redhead, and a blonde go into a bar.       
 The brunette says to the barkeep, "I'd like a BL."       
 The bartender replies, "What's a BL?"  
 The brunette answers in a snotty voice, "A Bud Light.  DUH!"
 So, the bartender dutifully serves up a Bud Light.  
 
 Then, the redhead says, "I'd like an ML."
 The bartender asks, "What's an ML?"  
 The redhead answers, as if to a slow child, "Miller Lite.  DUH!"       
 
 After serving the redhead, the bartender, now wary and alert turns to 
 the blonde. 
 
 She says, "I'd like a fifteen, please."  
 
 The bartender thinks and then says, "Okay, I understand that a BL is 
 a Bud Light and an ML is a Miller Lite.  But, I can't figure out what 
 a fifteen is." 
       
 The blonde rolls her eyes, tosses her hair and 
 answers, "Seven and Seven.  DUH!"
