Another Beer Please

Posted by michael on from the brooklyn-lager dept.

jmichaelg writes "What do you get when you combine a glass, a PIC computer, two capacitors, a coil and a zener Diode? A wireless beer glass that signals your waiter when you need a refill. The circuit is an RFID transponder that measures the fluid level in a glass and transmits a globally unique ID coupled to the fluid level reading when queried by an antenna hidden in your table. The query provides enough power to drive the circuit so no batteries are needed. A technical paper describes the circuitry in the table and the glass." This hit the news over a year ago, but we didn't have the technical details.

    This "news" is so old that Jay Leno has already delivered a similar joke on his show... about a year ago.

    "Oh, guk! OH, guk! OH GUK!" GNAAOMEBOY screamed it louder each time as guk shoved his penis farther into GNAAOMEBOY's bleeding anus.

    "UNF! UNF," guk yelled as he blew his load into GNAAOMEBOY's rectum. guk was about to thrust his throbbing shit encrusted penis up GNAAOMEBOY's asshole once again when the door flew open. guk spun around and in fright he blew his load across the room. It narrowly missed darkfyre who had just walked in.

    darkfyre shouted, "what are you doing with my man, guk? WHAT!" He was pissed. darkfyre reached down and pulled out a large kitchen knife.

  6. LANCE ARMSTRONG WINS HIS 5TH TOUR DEF RANCE by Anonymous Coward · · Score: -1, Offtopic

    I don't think my submission on Lance winning is going to go thorough, so maybe let's use this thread to give him homage.

    Have you noticed how it's become "chic" for your local sportswriter to claim that Armstrong isn't the "greatest" athlete of all time?

    As if he ever claimed to be?

      Can I rape them before you kill them? Only the female ones, because I'm a sexist. Which is much better than a racist.
