I Am A Regular Good Guy

and again, before we start I want to stress how important it is that we are not focusing too much on the actual humor you will derive when you get it, okay? Let's focus on identifying what has led to make others laugh, but not yourself. So for this, I will have to explain the joke.

Now, before I do this: I must caution you: if you want to laugh, then you're probably not going to. You see, if you didn't get it at first, then you might not get it right away.

Let's demonstrate with an example: Say you are a cart pusher at Wegman's, and you just read what you're about to read, but then.. all the sudden, it hits. You're pulling over to the side of the road, holding your sides, praying to God, Satan (I suspect the latter from you), whoever, to not get rear-ended by an 18-wheeler.
