I really don’t have any stories to compare.
One time, a relative and I were doing rural witnessing. As we talked to the householder, a goat put his head into my relative’s bookbag and started munching on a Watchtower. Of course, later, jokes about encountering “goats” in the ministry ensued.
I was working with a younger person and flipped open randomly in the Bible to some verse in Levites about cutting down trees or something. I joked with him that he should read that to the householder. Unfortunately, he took me seriously and did exactly that.
Not door to door, but still "ministry" related:
I had a “Bible study” I had with a poor man from another country…I brought another “brother” with me. During the study, a roach crawled across the kitchen table where we were having the study. The brother with me started to freak out. I attempted to brush the roach off the table with me hand, but accidently swept it right onto him. He leapt up and screamed like a girl.
Oh, another time, I was bringing this same study to the Memorial, but he had to get to work afterward and so he followed me. He often told me it took him an hour to get to work and I often wondered why. That was because he never drove over 30 miles an hour. In the country he was from, he never drove over that speed. So here he was following me at 30 miles an hour, where the speed limit was 45 and 55. We barely made it to the Memorial in time.
