As Taste and Whippit are leaving their apartment, Taste says "Don't let yourself get attached to anything you are not willing to walk out on in 30 seconds flat". This is a reference to a quote from the movie Heat (1995). William Fichtner, who plays District Attorney Frank Crenshaw, was in Heat.
In-jokes and obscure references: When Phil (Steve Carell) and Claire (Tina Fey) return to the restaurant claiming to be friends of Will.i.am they mistakenly call him Sam i Am. This is a reference to LA hip-hop producer Samiyam, who Collins (Common) is known to be a fan of.
