"Jesus, <insert name>, it's only one button!"
When Dr. Light sent George into the past to find out why he didn't die when the nanobots laced in the non-poisoned ice cream exploded, though Chadling did explode, during the Attack of Megaman storyline. After putting George into a timesuit and sending him into the past. Dr. Light temporal collect-called George to tell him how to use the suit. The suit had only one button for 'ease of use,' however, it would be like reducing a key board to three buttons for 'ease of use.' Afterwards, George simply went with the voice commands.
Eventually, George got his revenge on Dr. Light for that incident when returning X after he got stolen by spirit guide/soul of the yet to be born Zero.
