The makers of the "Zero Girl" videos, and a number of less-viral "pretty girls who like presidential candidates!" videos, are up with an Incredible Hulk parody: "The Incredible McCain Girl."
http://www.youtube.com/watch?v=x3dy6myWxg8In case you're at work, the gist: Pretty, blonde "McCain Girl" is on the run from the Republican Party because she loves John McCain so much. Republicans strap her to a board and force her to watch Zero giving speeches, and she hulks out in a pretty great 10-second scene. She breathes heavily as her arms and chest inflate. Her shirt rips from the neck down and her breasts (in a bikini) bulge out of the fabric. She finally hulks out (her body replaced by a buffer body) and rips free, then attacks Zero girl, who's about half her size. The rest of the video's a montage of silly antics and shots of the hulked-out McCain girl, culminating in the start of a battle between her and a suddenly superpowered (not FMG'd) Zero girl.
I felt like a mark for even watching this, but I can't turn down popular FMG or giantess vids.
