I used to fix phone lines for MCI -- I hated wearing those stupid polo shirts and wore my Dead tee shirts instead -- on several occasions while working, I would suddenly hear the boys playing on a customer's stereo -- worked great and made new friends too
At the Mollalla, Oregon Rodeo last summer, the first Bronk out of the gate bucked to "Welcome to the Jungle" by, uhhh, 'can't remeber but the guitarist is Flash. The next horse out bucked to the intro Jerry riff to "Truckin'" (as did several others that night). I was looking around for any reaction, but I think Me and whoever que'd up Truckin' were the only heads in the arena.
Speaking of "WKRP In Cincinnatti", I distinctly remember one episode where Dr. Fever puts on Shakedown and you hear maybe the first five seconds or so. Caught part of Touch of Grey on "Morning Joe" on MSNBC last week.
I worked for a Carnival one summer on the ferris wheel and every now and then The Dead would get played over the PA system. I would request it a lot, but only get it played every now and then. It was one of the Fillmore Sets.

Maybe doesn't qualify as heard... But on the FOX TV show Fringe, when the agent finally meets the mysterious charactor played by Leonard Nimoy in his home (office?), there was a set of photos mounted on the wall and there was Jerry and there was Brent at least behind him in the shot.
I'm a huge Colorado Rockies Basball fan. Apparently, so too, is the sound guy on the radio broadcasts on 850 KOA. He/she will play the Dead almost exclusively while going in and out of breaks. While this person is partial to ripping cuts from studio albums, I've heard everything from Touch to more obscure tunes. It's really cool.
