Nice contest!
My choice goes to:
https://steemit.com/freewrite/@whatisnew/weekend-freewrite-3-10-2018-3-prompts-father-o-brien-s-funeral
It's an extremely entertaining tale, it made me laugh heartily and I think it's written in a simple but effective way. It is not easy to put together a story that is consistent and has the right pace following the subsequent three prompts of a freewrite weekend. The only two times I tried it, I had to struggle a lot. That's why I think @whatisnew did a good job and deserves my nomination.
