Little girl asks her mum, 'Mum, can I take the dog for a walk around
the block?'

Her mum replies 'No, because she is on heat.'

'What does that mean?' asked the child.

'Go and ask your father. I think he's in the garage.'

The little girl goes out to the garage and says, 'Dad,can I take Lulu
for a walk around the block? I asked Mum, but she said the dog was on
heat, and to come ask you.'

He took a rag, soaked it in petrol, and scrubbed the dog's backside
with
it to disguise the scent, and said 'Ok, you can go now, but keep Lulu
on
the leash and only go one time around the block.'

The little girl left and returned a few minutes later with no dog on
the
leash..

Surprised, Dad asked, 'Where's Lulu?'

The little girl said, 'She ran out of petrol about halfway round the
block, so another dog is pushing her home.'
