Just when you thought you'd seen all The Simpsons episodes....

[Reality]

Or maybe you have. 
Saw this one for the 1st time, thought it was a very nicely done parody and a howl.
"Back to the 90's" or something like that.
Marge and Homer were dating at Springfield Place (Melrose Place).  Marge goes to college while Homer works at Grandpa laser tag place.  Marge falls for professor, Homer in turn is heartbroken so turns his 4 man singing quartet into the grunge band Sadgasm.  Total take off on Nirvnana.  The Sadgasm songs and video parodys of Nirvana are a hoot!

One of the better recent episodes.   The overly PC professor was hilarious.   "Let me tell you something Marge, everything penis shaped is evil!"
