As most of us know a great number of comics, let's share some laughs with those. It does not need to be badly written, out of character, forced by the editorial or whatever, just a moment when you would like to teleport inside the comic, grab the guy, give him a slap, and shout "ARE YOU NUTS??? WHAT THE HELL WERE YOU THINKING???!!!".
For example, one from the classics. Hulk #1. Rick Jones sneaks into the testing grounds of an atomic bomb and parked his car because some kids dared him to. I mean, that's a military base Rick, if you want to commit suicide there are surely many weapons around...
And to keep it fun, let's avoid "What was Marvel/The writer" thinking?" if possible, and rather stay in "What was that guy thinking?"
