Transformers: Dark of the Moon Easter Egg - Theme Song

At the part after Laserbeak pushes Jerry out the window, Sam and his boss have a talk. An employee in the backround is messing around with a new copier machine (which is actually Laserbeak in disguise). If you listen carefully to the beeping the copier makes, it plays the old Transforemers theme song, where it goes "robots in disguise."
