We have umpires at fantasy camp of course, they are college or minor league guys. With six teams, you have two per game, six total, and in the championship game, they have all six on the field, which is kinda neat really in a pointless kind of way. They enjoy it, we josh with them a fair bit, some of them recognize me with my white hair. There even is the occasional argument.
Last time, I was on first, with a runner on second with one out and the batter hit a pop up right at third base in fair territory. I was off the bag about 15 feet basically heading back to first when the third basemen misplayed it. He picked it up, stepped on third, and threw to second, I was so confused I wasn't even trying to run. Our coach had some words about the IFFR of course with the ump, who very clearly blew that call, and had some total BS about why it wasn't an IFFR at all. The pop up didn't even pass the baseline, it was "normal effort", the defender just misplayed it (it happens). It probably cost us the game, I was annoyed but didn't say anything.
