I used to think that Mormon missionaries were men who had received too many speeding tickets.
This came from a line of questioning when my dad had explained that "If you speed, a policeman might pull you over and give you a ticket."
Somebody giving me something for free, especially a "Ticket" (to a park? to a movie?) sounded like a good thing to me, so he had to explain further that "if you get too many tickets, you cant drive a car any more."
A few weeks later, I saw two men, dressed nicely with dress shirts, ties, and slacks riding bicycles.
I must have realized that they looked far to dressed up to be riding just for fun, and assumed they were going to work, but "must had received too many tickets" and couldn't drive in a car.
I didn't mention it for a long time, and would occasionally see pairs of men riding bicycles, and it just seemed obvious that, indeed, some people got too many speeding tickets and had to ride bicycles to work.
