It was a wacky world on the NBC '90s sitcom 'Wings.' Anything could happen on the ensemble show, from witty repartee to outlandish sight gags to a breathy romance or two.

'Wings' marks its 20th anniversary today, April 19. They were fun and funny times. The comedy revolved around Joe Hackett (Timothy Daly), a straight flier and owner of the one-plane Nantucket airline Sandpiper Air, his freewheeling brother Brian Hackett (Steven Weber) and transplanted Southern belle Helen (Crystal Bernard).

However, much of the charm -- and the humor -- at Tom Nevers Airport was supplied by a few fellas who would later become stars in their own right: Tony Shalhoub as the hopelessly romantic Antonio and Thomas Haden Church as Lowell the humble handyman.

Where are all the Coach fanatics? Let me hear it for my Becker obsessives! Who's got at least five syndicated repeats of Dharma and Greg in their DVR queue at all times? Anybody?

Cue the crickets.

Arthur Smith, a researcher with The Paley Center For Media, defines the aforementioned sitcoms as "middlin," or shows widely considered to be "forgettable ... programming [the] equivalent of end tables. They look fine in the room, but if they disappeared, you might not notice for a while."

Not that Coach or Becker or Dharma and Greg (or, for that matter, The King of Queens, Still Standing, or Yes, Dear) are necessarily awful shows. Granted, none of them could step foot in the shadow of the quality boasted by reruns of Arrested Development, The Office, or syndication staple Seinfeld, but obviously someone had to be watching them, right? ... Right?
