Apocalyptical Puns

It’s a catostrophe.

That would be a missed steak.

Hello,

I am requesting help with remembering a joke. Posts of this type did not seem to be against the subreddit's rules, but if I am in error, please let me know and delete my post.

Anyway, here is what I remember of the joke:

It is movie themed and it says something like this: "There should be a post-apocalyptic zombie movie with a romantic comedy element. Then we would have the world's first rom-com-zom-dom-bomb." The only thing is that I forget what the "dom" was supposed to mean and whether or not there is more to this joke, either in the set-up or the punchline. I googled it to no avail. Any help is appreciated.

Thank you

DAD: He was the mayor of Denver for a long time. They named the street Peña Boulevard after him even! It's crazy. I heard they even wanted to name town hall after him.
ME: But they didn't because of a scandal...?
DAD: Nah. They just felt weird naming it the "Hall of Peña". Get it, Jalapeño?
ME: ...
