<human>: Can you provide a brief overview of the text?

So I was running to the gym like I usually do, and on the way I had my Nike+ app turned on and my headphones in and I was jamming. As I was running down one road to get off base, there's another path that curves around some foliage that makes it impossible to see other people walking. Be that as it may, I had no shame to sing along to one of my favorite songs by the Lonely Island, "Dick in a box". 
As I'm running down this road, it's the beginning of my run and I still had a lot of stamina, so I had all of my breath with me and wasn't panting, therefore, my singing was extremely loud. Of course, as life would have it, a group of people were walking around that other path, and as I reached the intersection I see them laughing their asses off. 
Caught, with nothing else to say I go for the Canadian approach and say, "sorry it's my jam" and sprint off to get away from the scene. 
It was a good day lol.
<bot>: I was singing dick in a box while I ran to the gym and people heard me and laughed at/with me.
