As far as returning borrowed items, the physical item often serves as the reminder to return it. I am pretty good about having a "place for everything and everything in it's place." When I am done with something borrowed and go to put it back in its "place," that serves as the reminder that its place is at somebody elses house! If I now this isn't going to be practical, when I borrow the item, I put a task in the proper category (either @Home or @Office) that says something like "Return blender to Joe" and assign a date of when I think I am going to be done with the item.
As for the lottery tickets, I second the idea of dropping them in the tickler file for the date after the drawing.
