Can someone explain this reference to me please? (Season 2, Episode 7)
http://www.imdb.com/title/tt0859555/?ref_=nm_flmg_act_6
At the end of the episode when Det. Diana Ballard lets Sam and Dean go...
Dean: Does she look familiar to you?
Sam: No...
Dean: I'm hungry. I could really go for some pea soup.
I have a feeling this was a reference to a show/movie Linda Blair did in the past and this was a breaking of the fourth wall. Can someone explain this reference please? Thanks.
