I know this is pretty bizarre starting a thread about a riddle, but I go into this sandwich shop to eat and study a lot and they have these riddles they call 'Riddle of the week." I'm pretty good at getting them, but this one lost me, and I've been dying to know what it means. Here it is:
A man arrives in town on Friday, stays three consecutive days, and leaves on Friday. How can this be?
Can anyone figure it out?
