Radio and television announcers work under pressure. Sometimes they make hilarious errors. Yesterday, I heard a radio announcer, giving the weather forecast, announce very solemnly, "The high today is expected to be only 35. Current temperature is 36."
The first time I heard this, I chuckled and thought he just misread his script. But I heard the same thing two times in the next hour. Apparently, no one at the station was listening, or bothered to change the script.
