Last week, Glee’s 100th episode aired and surprisingly did not do as well as expected. It only attracted 2.8 million viewers. Wow! Were all the Gleeks busy that day?

The episode was filled with Glee classics including “Don’t Stop Believing,” “Valerie” and “Toxic”, so we are beyond confused as to what has been happening with the FOX show. The fifth season's ratings have been slowly declining.

Glee creator Ryan Murphy pulled out all the stops by bringing back original regulars Dianna Agron (Quinn), Mark Salling (Puck), and Heather Morris (Brittany), along with fan favorite special guests, Gwyneth Paltrow (Holly)and Kristin Chenoweth (April)

Other shows, “NCIS” and the premiere of “Dancing with the Stars” shattered Glee’s episode, with 17.1 million and 15.4 million views.
