Even if this isn't true, it still makes me laugh!
An elderly lady was having her dog sent to her with ABC Airlines. When the dog was unloaded in London it was discovered to be dead. Fearing that the elderly lady would be extremely upset the employees took it upon themselves to visit the dog pound and find a similar looking animal and hope the lady didn't notice.
When the lady arrived to collect the animal the manager decided that it might be a good idea if the lady got to see the dog from a long distance and hopefully by the time she got up close she wouldn't realise the switch. As soon as the lady saw the dog, she said "That's not my dog". The manager said "Yes of course it is madam it says so here on the paperwork lets go closer and I'm sure you'll realise that it is your animal". The woman replied "I know that's not my dog because my dog is dead!".
The embarrassed employees then had to retrieve the dead dog from a skip but the lady decided to keep the replacement dog!
