What Michael said is: You forget a thousand things every day, How about you make sure this is one of them? (You forget a thousand things every day, How about you make sure this is one of them? One of them. )

This sentence is the clue to the entire plot of GTA5 and comes from the Solomon movie Author's Penny Sanatorium (writer Penny's Medical Hospital). The original words are We forget a thousand things everyday, can't we just make this one of them? This movie can be seen in the cinema in the game and the original words can be heard.

This sentence alone is very interesting. No wonder Michael kept saying this during the robbery. Michael first says this during the prologue during the robbery of the North Yankton bank. Of course Trevor may have heard it from him many times, which is why he can make the correct judgment that Michael was responsible for the jewelry store case.

It can be seen from this sentence that Michael is a loyal fan of Solomon. In the end, Michael and Solomon teamed up to produce a movie, which was something that Michael was proud of in his life.
