Michael is very excited, and this is when he borrows from Eddie Money’s 1977 rock hit “Two Tickets To Paradise,” and sings his play on the lyrics to that song.
The moment in question takes place before Carol has left Michael heartbroken.
He’s bought two tickets so that they can do a couples trip to a Sandals resort, and is in the middle of a happy talking head interview when he details his plans for the “all-inclusive” trip.
Unfortunately, Celotta had no idea that a two-line snippet of the song (which even had the lyrics changed a bit to fit the scene) would need to be approved so that The Office could use it without later having to worry about copyright infringement.
