If 'Glee' has you yearning for more song-and-dance routines on TV, hold onto your (top) hats! From April 29 to May 5, Fox is turning several of its shows into musicals, including 'Bones,' 'House,' 'The Simpsons,' even 'Fringe.' On May 2, 'Family Guy' will celebrate its 150th episode with an extended episode featuring new and familiar musical numbers. Suffice to say the shows should be a blast, for both us and the actors.

Of course, TV aficionados know this is nothing new. Shows like 'Ally McBeal,' 'Eli Stone,' and 'SpongeBob SquarePants' have featured musical numbers regularly, and I'd be remiss if I didn't mention 'Viva Laughlin' and 'Cop Rock' (even though the latter was declared by TV Guide to be one of the worst shows ever, ouch!). In fact, we can trace the trend back to classic episodes like Bugs Bunny's 'The Rabbit of Seville' and 'What's Opera, Doc?'
