Although TV has seen a resurgence of musicals in recent years, a series doesn’t have to be Glee or Smash (may they RIP) or Crazy Ex-Girlfriend to feature singing and dancing. In fact, the musical episode has a fine history of adding a little razzle dazzle to non-musical shows throughout the years — to both wonderful and disastrous effect.

Sometimes the format works, like in ABC’s fairy tale fantasy Once Upon a Time  episode “The Song in Your Heart” (the network’s The Middle will also break into song in an upcoming episode), and sometimes it doesn’t, like the completely unnecessary late-season 7th Heaven episode.

Below, find a list of some of television’s most notorious musical episodes from non-musical shows. Which one is the best?
