Transformers: Revenge of the Fallen (2009) Easter Egg - Terminator in Transformers

Go to about 2 hours and 7 minutes and you will soon notice a a robot who will shoot around, do a tuck-and-roll and die. The interesting part, however, is that if you look at its arm right after it dies, you will notice the number T-1000.
This was put in because Michael Bay (the director) felt that the new Terminator movie was copying Transformers (which is why it dies).
