Girls Gone Butch

Yes it's a "South Park" crossover. As you can see with LesBos bar and Cartman being abducted by aliens. 
I had to throw in some lesbian jokes and references (as a lez myself, I loved this drawing)
Butch Wax is a reference to a wax men used in the 50s and 60s for their crewcuts www.mikanet.com/museum/images/…
Lipstick Shoppe is a reference to Lipstick Lesbians
Fish Patties is based on an old joke
From left to right:
Rebecca Gillies as Rachel Maddow (she had to pin her hair back a lot)
Bridget Jones as Ellen DeGeneres (with the old hairstyle and looks a lot like Kate McKinnon's SNL impersonation) cdn-media.ellentv.com/2013/04/…
Shazzer as Martina Navratilova (congrats on the engagement Mart!)
Jude Russell as k.d. lang (early 90s)
