A likely story! – Russian translation

так я вам и поверил!; так я тебе и поверил! ("Is one to have no privacy, Glossop?" I said coldly. "I instructed Jeeves to lock the door because I was about to disrobe." "A likely story!" said Tuppy, and I'm not sure he didn't add "Forsooth!" "You needn't try to make me believe that you're afraid people are going to run excursion trains to see you in your underwear." (P.G. Wodehouse))
