Transcription
[[Inside an office for GPF. Dexter is standing on the ceiling, a blond-haired Ki with a heavy coat and a dark-haired Fooker using an iMac are kissing. A dove flies overhead and a chandelier hangs from the ceiling. Dwayne stands in the doorway with a purple mohawk and a "Computers stink!" t-shirt. Trudy smiles, wearing Ki's clothing and a heart tattoo, and is holding a PERL book. Randi the wonder kitty has a mouse, while Fred is speaking with Nick, who holds a cookbook, has a Dilbert tie and an earring. A car is parked inside, and a computer and "Teamwork" poster are upside down.]]
