The little girl's name Blanche is also the name of the main character from the play A Streetcar Named Desire. Cam says "I can't believe I'm just about to say this, but you're going to have to rely on the kindness of strangers", this is the most well known quote from Blanche. Also Cam screaming "Stella!" and wearing a white shirt and jeans is a nod to the play (and the movies).
This is the first appearance of David Cross as councilman Duane Bailey - however his name tag on the table says "D Rogers."
Looks like the whipped cream smiley face Mitch puts on Cam's shirt was done in more than one take as you can see a smiley face stain on Cam's shirt prior to Mitch using the whipped cream.
