If 2 dads and 2 sons go to a shop and bye a mars bar each costing 50p each it cost them Â£1.50 how is this posible.
They're 2 sons and one dad, the reason there's 2 "dads" is because each son has got their own dad? So they're only 3 people? :D
I know this, one dad is the grandpa, the son of him is the dad, the dad is the second dad and the son is the second son.
