After taking the stage together for Robert Downey Jr.'s Generation Award at the MTV Movie Awards on Sunday, the Avengers: Age of Ultron cast stayed together for an appearance on Jimmy Kimmel where the late-night host gave them a peek into Avengers gay erotic fan art. Of course the resident scientists of the group, Tony Stark and Bruce Banner, have a little thing going on. Chris Evans fails to fight off the giggles the entire time and Chris Hemsworth says it looks like it's "just another day on set." Then Kimmel shares the fan art of a few of the other heroes nude, obviously, with the strategic placement of some accessories. After seeing Captain America shrouded only by an American flag and Thor with Iron Man's mask in front of his crotch only one thing is certain: an Avengers calendar needs to be done for charity. Any charity. Just give us the damn calendar.
