Bruce Wayne, Gotham's darling, aka Batman, realizes that his new bodyguard is strange. Very strange.
World War II veteran Steve Rogers, aka Captain America, realizes that his new employer is strange. Very strange.

A penniless centenarian looking for work spots a piece of paper blown down by the wind. It reads: Wayne Enterprises is hiring a personal bodyguard for its CEO.
Rogers: We need a plan.
Brucey: Great. I have plans A through G. Which one do you want?
Rogers: ...
Brucey: Just one last cookie. I promise, Alfred.
Alfred: Watch your figure, Master. Oh, I mean, sir. I've already had three suits remade for you. If you put on any more weight, you won't even be able to fit into your Batsuit...
Rogers: Another plate of cookies, please, Alfred.
Alfred: Of course, Mr. Rogers.
Brucey: ??? How come?
Rogers: Because I don't gain weight.
