Several years ago, we were behind schedule due to a late campground departure earlier in the day; and we were lost in Colorado Springs. My wife was toying with a new Garmin GPS that we had bought for our Prius, and we were navigating with both the Garmin and the built-in navigation system in our Tundra.
In any case, it was dark, and it had just started snowing; so there was a little pressure to find the Costco quickly, refuel and get back on the road to Denver where we had people awaiting our arrival.
As you can probably guess, as soon as we pulled off of I-25 onto surface streets, the two GPS's started to disagree on the shortest route to the Costco (which, some time later, was further complicated by there being TWO Costcos in Colorado Springs).
The further we got from the highway, the more frantic the button pushing got on both GPS's, accompanied by conflicting directions on where and which direction to turn, and the Garmin's constant computerized comment, "RECALCULATING..." and the Tundra's instructions to "Make a legal U-turn and ...". (For those unfamiliar with these GPS's, the Garmin lets you continue on the alternate route you've initiated, and it recalculates new instructions based on your current location; while the Tundra wants you to go back where you screwed up and turned the wrong way, so it can continue on the original route that it calculated when you first entered where you thought you wanted to go.)
I'm a little hard of hearing, so I kept asking my wife "What was that?", "What did the GPS say?", What did it say to do?"; and my wife just kept faithfully repeating the Garmin and Tundra GPS's comments.
After getting thoroughly lost and close to running out of gas, and with the snow increasing in intensity with every passing minute, the frustration level was getting pretty high; and after stopping at a traffic light, with both of us just short of screaming at each other, we looked at one another, stared for a second or two, and immediately broke out laughing!
Both of us had simultaneously recalled the conference room scene from the movie "Galaxy Quest", where communications officer "Gwen DeMarco" (the equivalent of Star Trek's Lt. Uhura) realizes that her primary job is to just repeat what the computer says. "Look, I have one job on this lousy ship! It's stupid, but I'm going to do it! -- OK?!"
In any case, we now only use one GPS at a time. We use Google Earth for trip and route planning, the Garmin is for enroute instructions, and the Tundra navigation system is just for figuring out where we are when we get lost.

Note: While searching YouTube, I found another clip from this movie that newbies will find amusing. After all, we were all newbies at one time; and I think each of us can recall pulling our first RV into or out of a campsite when we thought every person in the campground was scrutinizing each move we made:
