The Manchester Lad....
A lad just getting home from school runs up to his dad...
"Daddy, daddy! I'm the only one in my class that can count to ten. Why do you think that is? "Why that's because you're from Manchester son." The dad responds.
The next day the lad gets home from school...
"Daddy, daddy! I'm the only one in my class that knows all the letters of the alphabet. Why do you think that is? "That's because you're from Manchester son." The dad tells him again.
The next day the lad bursts through the door...
"Daddy. daddy! I'm the only one in school who has a large penis, is that because I'm from Manchester?"
The dad looks at him and says, "No son that's because you're 27."
