Heard this great story ("friend of friend", so make of it what you will):
Woman is looking after friend's dog while owner on holiday. Of course, the dog dies. The woman phones the vet, who is sympathetic: "Don't worry", he says "I know that dog – very elderly, not 100% well, no surprise".
"What do I do now?" asks the woman. "I can dispose of the dog if you bring it in" is the vet's response. "But I don't have a car" says the woman, "How do I get it to you?". "Just bring it in on the bus" advises the vet.
It's not a small dog, but the woman finds a cardboard box that will do the job. The puts the dog inside, tapes it up, then places the box in a large carrier bag.
She heads down to the bus stop, where she struggles to get her awkward cargo onto the next bus. A helpful bloke offers assistance: "Do you want a hand with that?" he asks, as he lifts the box onto an overhead luggage rack."Wow, it's heavy! What's in there?" The woman can't tell the truth: "A stereo", she says, thinking about what originally came in the box.
The woman reaches her stop, which happens to be the same destination as the helpful stranger. "Let me get that for you" he says, lifting the heavy box down from where he had placed it. The two passengers get off the bus, whereupon the bloke sticks the box under his arm and runs for it, no doubt excited to have obtained a stereo through his deceitful act of generosity.
I wonder if he was disappointed…
