What is a joke setup that couldn't possibly have a punchline?

This is a long one, but here we go!

So there's a Cheerio named Larry. Larry is in college and got an internship at a brand new company. To celebrate, Larry went to the supermarket to get some oats and milk, because yaknow, he's a Cheerio. So some time goes on and Larry graduates college, and the company he worked for said "Hey, you did go work for us as an intern and we're growing, would you like a part time job?" Larry of course accepts the job and is happy as could be, so to celebrate he goes to the supermarket and gets himself some chocolate and milk, because yaknow, he's a Cheerio. More time passes and Larry's boss says "Hey Larry, you've been doing great as a part timer, but as you know we're growing and we were wondering if you'd like a full time job." Of course Larry accepts the job and is really happy about that, so he goes to the supermarket to celebrate and gets some fruit and milk, because yaknow, he's a Cheerio. More time passes and Larry's boss says "Larry, you've continued to do great work for us and we're still growing, how would you like to be a manager?" Of course Larry is excited and accepts yet another promotion. To celebrate, he goes to the supermarket and gets some honey oats and milk, because yaknow, he's a Cheerio. More years down the line his boss comes up to him and says "Larry you're still doing great work for the company and as you know we're still growing, would you like a job as an executive?" Larry accepts the job with much enthusiasm and goes to the supermarket to celebrate. He gets himself some sweet toasted oats and milk, because yaknow, he's a Cheerio. Once again years pass and Larry gets a personal call from the CEO. This was odd, but he was invited to the CEO's home for lunch. During lunch the CEO says "Larry, I know you've been with this company from basically the beginning, and have done fantastic work for us. As you know, I'm growing old and plan to retire soon. With that in mind, I'd be honored if you'd take my place as CEO in my absence." Elated, Larry accepts the job and sure enough because the CEO. So to celebrate Larry goes to the supermarket to celebrate, because yaknow, he's a Cheerio. This time though the supermarket is really crowded, so he asks an lady cashier what's going on. "Oh its free sample day! Just make a line at any of the tables to try anything at the store!" Larry thinks this is a great and fun idea, and he's in the mood for some fruit punch. He walks around but doesn't see any. So he goes back to the cashier and asks where it is. She says "Sorry sir, there is no punch line."
