MOVIES ON DRUGS
The Avengers are on cocaine, including Tony Stark. Cap and Tony are on a rooftop and Tony is exclaiming how "awesome" the feeling of being high on cocaine is. Tony is so elated that he feels that he can fly. Cap warns him that he needs his suit for that, but the billionaire dismisses it and jumps, dying on impact with the ground.

EVERY SUPERHERO EVER
Cap is standing with the rest of the Avengers as they talk about how nice it is to have their own movies.

IF MARVEL CHARACTERS WERE REAL
Cap approaches Doctor Strange and asks the wizard for a prescription for some ibuprofen, claiming that he is sore from the fight against Thanos. Strange declines, tired of being asked for prescriptions, but relents and writes one for Cap (as well as for some oxycodone at the super soldier's request). Strange rudely hands the paper to Cap, who runs off to get his medication.
