When I arrived at a friend's home for a party, my old rattletrap looked pretty shabby parked next to all the fancy new vehicles there.
I announced to the other guests that they'd have to excuse my transport, but my gardener had requested my Rolls-Royce for a special occasion and so we had traded cars for the day. Another partygoer said that he, too, had switched cars. He said he had loaned his Rolls to a friend who wanted to impress a new girlfriend.
Everyone laughed, and I felt rather pleased with my little joke, until a few days later when I drove past the same man.
He was driving a Rolls-Royce.
