Yes, the original song is really THAT boastful. First of all, it insults the people who refuse to “dance the Rhythm Steps” by calling them dunces. Second, it calls the dance “simple as ABC”, and uses the exclamation “whoa!” in describing it. And to top it all off the singers exclaim “Simple as the day is long!!” as the very last lyrics that are sung, right before the end, which is completely irrelevant to the topic at hand. A comparison between the length of the day and this obscure dance (two steps forward, one step back) does not tell the 21st-century listener ANYTHING useful about how to actually dance to it. Maybe at the time it was exciting. Nowadays this song is just perfect fodder for AmIRight.

While AJR might have not been famous when they wrote this song, they're boasting about the fact they're not famous
