The text on the button "We Will Make You An Offer You Can't Refuse" is a reference to the much-repeated line in the classic The Godfather trilogy, written by Mario Puzo.
The first occurrence of the line "I'll make him an offer he can't refuse" was in the scene when Johnny Fontane, a famous singer passing his prime, asked Don Vito Corleone, the Godfather, for help to secure him a role to boost his fading career. Don told Johnny not to worry about the head of the film studio and said:
"I'll make him an offer he can't refuse."
Then in the most memorable scene of the movie, the studio head wakes up to find the bloody head of his racehorse in his bed, and Fontane is subsequently given the part.
