The most epic scene of Avengers: Endgame is highly debatable. Some think that Captain America using the Mjolnir was the most epic scene while others think that Iron Man snapping Thanos and his army out of existence was the most epic scene. Sadly, Iron Man snapping Thanos and his army out of existence might no longer be an option for the most epic scene of Avengers: Endgame because most of us misheard Tony Stark. When Tony snapped his fingers, most people heard Tony saying, “I am Iron Man” but that’s not true. He actually said “I’m GPA 5” and the reason behind it is simple, before dying, Tony wanted to flex his educational credentials and that’s why he wanted his last words to he “I’m GPA 5”.
