Just read this joke, from a youtube comment. I assume/hope they don't mind me copying it here. N.B. Not written by me. Not using quotes, to make it more easily read.
Sergei Mikhailovich is struggling down the escalator at the Tsvetnoi Bulvard Metro station in Moscow with two very large and heavy suitcases when a man standing just behind him asks the time.
Sergei Mikhailovich sighs, puts down the suitcases and glances at his wrist.
“It's a quarter to six,” he says.
“Hey, that's a pretty fancy watch!” exclaims the stranger as they step off the escalator.
Sergei Mikhailovich brightens a little. “Da balshoe spasibo. It's not bad. Look at this,” he says and points to a time zone display that covers the 24 time zones as well as 50 major cities. He then presses another pushbutton and a voice says “Il est quatre heures moins quart à Paris,” with a perfect Parisian accent. Another pushbutton gave the time in Japanese.
The man is amazed by the features of the watch and stands with his mouth open in admiration. “That's not all,” adds Sergei Mikhailovich as he touches a section on the sapphire crystal and a tiny map of the Moscow Metro system appears on the display. “The flashing dot shows our location by Global Satellite Positioning.”
“You have to sell me the watch!” the man says eagerly.
“Oh, it's not for sale. This is only the prototype and I'm still perfecting it,” Sergei Mikhailovich explains. “Look at this,” and he plays the FM radio receiver, shows the sonar device for measuring distances, the paper printout of data and, astonishingly, how to play audio recordings of books.
“You have to sell me that watch!” the man pleads.
“No, I can't; it's not completely finished,” Sergei Mikhailovich tells him.
“I'll give you 50,000 roubles for it!”
“No, no, it cost me more than that to make.”
“100,000 roubles then!”
“I'm sorry, I can't it's only the prototype and ...”
“I'll give you 500,000 roubles for it!” And with that, the man takes out a wad of notes and peels of the amount. Since the prototype cost about 100,000 roubles to create and develop, Sergei Mikhailovich quickly calculates that with the 500,000 he can make two more and have them ready for the Russian market within just a few months.
The man offers the money to Sergei Mikhailovich. “Come on, take it. With 500,000 roubles you’re making a handsome profit.”
“Okay,” Sergei Mikhailovich pockets the money, takes the watch off his wrist and hands it to the man.
The man straps it on his wrist and starts to walk away,
“Just a minute,” Sergei Mikhailovich calls after him. The man turns around and Sergei Mikhailovich points to the two suitcases he was carrying.
“Don't forget the batteries.”
