Sharper than a serpent's tooth?

[donmurray]

A little 10 year old boy is walking down the street when a motorbike pulls up beside him

"Hi son " says the biker "Want to go for a ride ?"

"No, go away" replies the boy, and walks off down the street.

The motorbike pulls alongside the boy again , and the biker says

"Son, if you come for a ride with me I'll give you a bar of chocolate"

"No, go away" replies the boy, and walks off down the street.

The motorbike pulls alongside the boy again, and the biker says,

"Son if you come for a ride with me, I'll give you a bar of chocolate, and £5!"

The boy turns round, looks at the bike and says;

"Look dad , you bought the Harley, you ride it!"
