Like, an actual grown man. Dressed as Iron Man.
So this is a thing that happened.
"Hey, this seems like a good choice of outfit to wear to a baseball game. You know what would really seal the deal? No helmet. Boom. Most iconic part of Iron Man, right out the window. Really gets people thinking."
I'm really, really hoping that the heckles were all Iron Man puns. "HEY TROUT! YOU SUCK! YOU REPULSOR ME! I HAVE A STARK OUTLOOK ON YOUR CHANCES TO SINGLE IN THIS PLATE APPEARANCE! YOU ARE EXTREMIS-LY UNTALENTED! YOU MAY WEAR RED BUT YOU'RE NO CRIMSON DYNAMO! Uh ... armor."
