While Frank and Carl are flying back to the US Frank looks out the window and tells Carl that they are over Fiorello LaGuardia Airport and runway Number 44. All runway ends are painted/labeled based on the compass direction or bearing it is facing or heading. A Due North is runway "36", meaning 360 degrees and the opposite end marked "18", for 180 degrees. Runway numbers include 1 to 36. No runway 44 exists.
During the "Go Fish" scene, Cheryl Ann negotiated $1000 for Frank to spend the night with her. She asked him to endorse his $1400 cashier's check (fake) over to her in exchange for $400 cash in return. However, he did not actually endorse the check with a signature before she took it from him. This may have been intentional to show that Cheryl Ann was not paying attention to detail.
