"Whistle While Your Wife Works" followed Peter as he had to deal with adverse work conditions after blowing his fingers off with fireworks. Being that he couldn't type or stay concentrated, Lois came in and lent a helping hand. Meanwhile, it is found out that Brian is dating a "moron" guest voiced by Drew Barrymore.
As always these plotlines were accompanied by a fair amount of flashback/manatee gags which were less funny than normal (excluding the hilarious use of Tim Curry's Lord of Darkness character from Legend). As mentioned only one of the storylines was really funny, and that was the one that featured Brian's girlfriend Jillian. The other story with Peter and Lois was really not funny at all, and seemed to be a step off from most of the material that the show normally airs.
The choice of Drew Barrymore as the voice of the ditsy beautiful blonde was perfect, and it wasn't much of a stretch to match the voice with the character. But what really made Jillian such a great character was her interaction with the Griffins. She matched stupidity with Peter and Chris, while acting as an endless source of comedy for Lois and Stewie. And in the end, Brian couldn't get rid of her, which is perfectly okay with me as we hope that Jillian is kept around for as long as possible. It has been a while since Stewie and Brian's interactions have been this fun, and the ever-present addition of the dumb girlfriend could really help in continuing Stewie and Brian's spiteful relationship.
Another topic that was pretty humorous in this episode was how they made fun of mediocre films. In three separate scenes bad Hollywood movies were glorified by the main characters. The first film was You, Me and Dupree, which Peter always discussed about with Cleveland at the beginning of every work shift. The second film was Along Came Polly which Quagmire would dictate scene by scene to Peter in the middle of his work day. The third film was Mr. 3000 which Jillian couldn't get to work in her DVD player. The mention of all these movies seemed like a way for MacFarlane and the Family Guy writing staff to sort of make fun of the rousing support for mediocre films from the broad audience.
Plus along with these three movies there was a large segment dedicated to the television show Wings, which although not a film, was also an average show that was embraced in the episode (by Quagmire). This wasn't the best episode of Family Guy, but it wasn't bad either.
