Soon Noah is invited to a party to have sex with his supposed girlfriend Marisa (Ari Graynor) who uses him only to get oral sex, she agrees to have sex with him if he brings her drugs to the party. Noah, tempted by the offer, steals Mrs. Pedulla's car and takes the kids to the city, where he meets Karl (Sam Rockwell) in his body building shop. Karl likes to hide his cocaine in expensive baby dinosaur eggs and loves to make new friends. After getting drugs, he realizes that Rodrigo has stolen an egg from Karl, after a struggle the egg burst open wasting all the drugs. After Karl finds out the drugs are missing and calls Noah, finding his number on Facebook, he tells Noah that he has to come up with $10,000 or he will kill him. Noah, in a panic, decides to take the kids back to their parents but thinks against it feeling he has to fix his own problems. He then takes the kids to a bat mitzvah (which Slater was invited to earlier in the movie) for a bratty popular girl who goes to school with Slater. There Slater sees his friend, Clayton (Alex Wolff), who lied to him earlier saying that he couldn't hang out with him because his spider died. Clayton admits he lied because he was sick of hanging out with him at his house and not going anywhere, which hurts Slater's feelings.
Noah, is not your typical entertain-the-kids-no-matter-how-boring-it-is kind of sitter. He's reluctant to take a sitting gig; he'd rather, well, be doing anything else, especially if it involves slacking. When Noah is watching the neighbor's kid he gets a booty call from his girlfriend in the city. To hook up with her, Noah takes to the streets, but his urban adventure spins out of control as he finds himself on the run from a maniacal drug lord.
