Epiphany.
We all know dullards. They're everywhere. All ages, races, sexes, sizes, shapes. They might be intelligent, attractive, or successful, but they're boring conversationalists. When you interact with them, you sometimes find yourself questioning whether the person's DNA is piggybacked with a single complex algorithm that's dictated what they've done and what they've thought about their entire life. They might be talkative, they might be emotional, but they're missing that certain spark.
These poor dullards never experience an epiphany unless they smoke weed, and they forget them ten seconds later anyway. Epiphanies are what make humans more than just smart animals. Sometimes they come as a result of contemplation, experience, or accumulation of knowledge that stretches across minutes, hours, days, even years. They can be important to human progress ("I am going to get a bunch of metal and lightning together and make the Internet"), important to our understanding of our place in the world ("what am I doing with my life"), profound ("I see God"), batshit insane ("I actually seriously see God in real life"), or inspiringly trivial ("This beer tastes like Vikings died in it").
Danny's opinions tended to fall into that last category, but they were still epiphanies, damn it. "It's embarrassing as fuck to have an ass" is not especially profound, but it forced itself out in a spirit of self-conscious clarity. You've probably never felt shame simply for possessing a particular body part; not only did he do so, but he articulated it. It's quite possible that that sentiment never existed until he said it, and considering how long we've been around, it's worth recognizing.
"Ronald McGoddamnDonald" holds a similar spirit. We've all grown up with Ronald McDonald. I don't know about you, but he's just always been there. I've seen him before, I know what he looks like, and I could tell you what color his shoes are without looking, but have we actually paused for a moment to think about him? Remember, if you stared at his cardboard stand-up stoned and slack-jawed out the car window as your buddy Schmo picks something up at the drive-thru at one in the morning, it doesn't count.
After watching a few minutes of the obscenity-laced, perpetually troubled, old, fat, white guy named Danny, we'd probably make a snap judgment and assume he was a homophobic bigot, among other things. "That just means she likes what I like" is an epiphany of reconciliation between himself and people who are different. It just might have been fueled by the interest that "normal" people showed in him.
It's a stretch for me to say that Danny's enjoyment of a corn dog during said epiphany was ironic commentary. I just think it's funny.
