Phillippe plays a female weightlifter, and at least one of the male announcers (played by Jason Sudeikis and Will Forte) seems strangely attracted to her. "She is a beautiful lady," says Forte. "I have never felt this way about a woman before."

Forte admires her "shoulders, those tree-trunk thighs." Adding, "she is just full of spunk."
