[Dean walks up to the counter]
DEAN: I gotta place an order.
JESS: Talk into the clown.
DEAN: I am.
A reference to the clown head at Jack-in-the-Box fast food restaurants that customers spoke into to place their order at the drive-through service. This option existed from the early 1950s to the early 1980s. It seems slightly odd this is a handy reference for someone born in 1984. Dean gets in a lot of insults to Jess in this scene.
