A man is mending a puncture on his car watched by a neighbours' young lad. "What's that?" the lad says " A screwdriver" says the man "I use it to remove the hubcap." "My dads got two of them" says the lad.
"Whats that?" "Its a car jack for lifting up the car" "My dads got two of them.
What's that then?" "Its a wheelbrace, I use it to loosen the wheel nuts" "My dads got two of them" says the lad.
The man decides to take a leak behind the fence and he sees that the lad is watching him. "I suppose your dad has two of these" says the man. "No just the one" says the lad "But his would make two of what you've got there."
The lad's Dad is a bit mean, all this kit yet his lad doesn't know what any of it is for - so Dad obviously ignores and/or discourages the lad's questions. Miserable sod.
