    Redditor u/GitEmSteveDave provided the noteworthy context via an article from MTV News:

I had that, and this big soda, and I thought something really bad was going to happen." The actor then said that at that moment of clarity, he tossed all of the drugs in his car into the ocean and got cleaned up, claiming that the "American cheeseburger" scene from Iron Man was a special tribute to Burger King saving his life.

    Many MCU fans had probably forgotten this monumental cameo, or else it never registered for them since Musk was far less famous when Iron Man 2 came out. According to Redditor u/liavz123, "Robert Downey Jr.(Tony) met Musk and toured the SpaceX facility to help Downey’s interpretation of Stark. It was so helpful that they invited Elon to do the cameo."
