Another Joke just E-mailed to me

a young boy comes home from school and asks his dad to help him with his homework.

"dad", he said, " whats the difference between potential and reality???"

the dad thought, and said " go and ask you mum if she would sllep with the milkman for £10000 "

the son does as hes told and comes back, "she said yes dad

the dad smiles and says, "go and ask your sister if she would sleep with the milkman for £10000"

the son, goes away puzzled and then returns and says " she said yes dad!"

"can you help me now?"

"no" says his dad, " go and ask your brother if he would sleep with the milkman for £10000"

the boy comes back and say " he said yes dad, now can you help me with my homework?"

"ok son, here it is" replied the dad.

"this family has the potential to earn £30000, the reality is that we are living with 2 slags and a hom!!"
