Mamma Mia

I have developed an unhealthy obsession with Mamma Mia.  I have now seen the movie twice and purchased the soundtrack on itunes.  What is wrong with me?  I mean, its an amazing movie and all, but seriously?  Furthermore, I have also spent way too many study breaks singing the songs and working on dance routines, specifically to the title track "Mamma Mia."  I want to be Meryl Streep when I am old.  I really need to be done studying.  I want my sanity back.
