"Your authoritative time check--after a pause..."

In the mid '80s, I'd adjust the AM radio so I could hear WLS from Chicago.  At the time, I thought the station had an interesting mix of music and personalities.  Morning DJ Larry Lujack and evening DJ John Records Landecker were two of the station's more memorable announcers.  Oddly, one aspect of Lujack's announcing that stood out to me was the way he'd announce the time.  Sometimes, his entire intro would involve waiting five seconds into a song and announcing, "6:11!"  To this day, I haven't heard any other DJ announce the time that way.  I'm still not entirely sure of my own blood type, but Lujack's unusual combination of minimalism and authority has stayed with me for over three decades.  Who knows how the mind works?
