40 Gypsies arrive at the Pearly Gates in their Transit vans and caravans.
St Peter goes into the gatehouse and phones up God, saying. 'I've got 40 travellers here. Can I let them in?'
God says 'We are over quota on gippos. Go out and tell them to choose between them which are the 12 most worthy, and I will let just the dozen in.'
Less than a minute later St Peter is on the phone to God again.
'They've gone', he tells God.
'What?' says God, 'All 40 of them?'
'No, the gates'.
