Rather than pigeonhole himself into one style of comedy, the 32-year-old Tucson native sees his act as more of an observational comedy show that he can adjust to fit what he thinks the crowd will want to hear.
"It's just shit I think is stupid. I say what people were thinking. I'm always looking for new material, but you have to find what's funny to everyone, not just you. I try not to be offensive intentionally, but I just use what I see," Casillas says. "I try to be relatable as much as I can, so I'll read the audience and say stuff based on that. Like I have the drunken stories, but I also have the jokes about having a kid and being married, the whole spectrum. Sometimes you surprise yourself and make people laugh that you didn't think would laugh, that's the best part."
For Casillas, the toughest part about performing is the fact that he misses some important moments in his 3-year-old daughter's life.
"It's cool to me to be on stage, but it's hard sometimes when I'm gone for a weekend and she'll grow while I'm gone. It might not be something big, just a new word or something like that, but it feels like a lot when I miss it," Casillas says.
Keeping that in mind, Casillas knows that comedy has brought him some opportunities that he never thought he'd get.
"I'm from the south side of Tucson, so it was hard to see me going anywhere. I'd never been on a plane before I started doing comedy," Casillas says. "I did New Year's Eve in Albany at the Palace Theatre and there were like 1,700 people there, all dressed up in this fancy theater. I turned to the manager before I went on stage and said 'You know I'll be making dick and fart jokes, right?'"
At this point in his career, Casillas has opened for some of the biggest names in comedy at just about every metro Phoenix comedy club, but he still maintains his day job of managing an auto body shop in a suburb just outside of Tucson. He believes it helps him work on his interactions with people whom he wouldn't otherwise have conversations with.
"It's great because it's all old people, so they just hit their cars on shit all day. I've always been good with old ladies. They see the tattoos at first, but then they can't resist how charming I am," Casillas says. "It's good for relating to people you wouldn't otherwise relate to, like for shows like [the opening weekend at House of Comedy]. I never thought I'd be in a room with a bunch of millionaires."
