||The staff at an old people's home was puzzled when one of the residents began gargling with TCP. They asked her why but all she would say was that something had happened at the post -office. This is what actually occurred.
The old lady, who rarely ventured out, had visited the post office to post a letter. She bought a stamp, and since there was a long queue behind her she stepped aside. She put her change in her purse, licked the stamp and put it on her letter. Despite pressing and thumping and licking it again, the stamp failed to stick.
"Excuse me, this stamp won't stick," said the old lady.
"You need to peel the paper off the back," explained the clerk.
The old lady put on her spectacles, fiddled for a few seconds to peel off the backing paper - and then licked the stamp again.
"It still won't stick," interrupted the old lady again.
"It's a self - stick stamp," said the assistant.
"Well this one isn't sticking at all - there's something wrong with it," demanded the old lady.
"Well it won't stick now because you've licked it."
"Well I'm totally confused now," said the old lady.
"Just give it here and I'll post it for you," said the cashier, and doing her best to explain continued, 'These new stamps don't need licking. They are self - sticking. They save time. They are already sticky."
The old lady continued to look blankly at the assistant.
"Look," said the well-meaning but desperate post-office clerk, "Just imagine they've already been licked..."
This sent the old lady scurrying out of the door and across the road to the chemist.
