OK, so Stan Lee makes a cameo appearance in each film in the Marvel series.

But what are the odds that he would drink this drink that Bruce Banners blood was accidentally tainted with in The Incredible Hulk (2008)?

I can certainly see him appearing in many movies as an extra, but him drinking that drink in hulk is just to much of a coincidence for me.

Any out of universe information on his roll in this film? What are the odds on him being the guy who drinks Bruce Banners Blood?

Stan Lee makes a cameo appearance in each film in the Marvel series but isn't it incredibly unlikely that he would have been the person that accidentally drank Bruce Banner's blood (the blood that accidentally tainted a bottle of energy drink)?

I can certainly see him appearing in many movies as an extra, but him drinking that particular bottle just beggars belief.
