Have you ever had to call Uber's help line after leaving your phone, camera, or wallet in a driver's car? If so, you're far from the only one. These are the three most commonly forgotten items among Uber riders, according to Uber's new Lost & Found Index for 2019.

While this in itself is unsurprising, Uber's annual analysis is full of offbeat findings. For instance, East Alabama is the most "forgetful" region in the U.S., followed by Gallup, New Mexico, and Cookeville, Tennessee. Boozy holidays like New Year's and Halloween are the most forgetful days of the year, and people are more likely to forget their watches on Mondays, their passports on Fridays, and their cakes on Sundays.

And these are the more mundane objects discovered by Uber drivers. The taxi and ridesharing service also rounded up a list of the “50 most unique lost items,” and it leaves us with more questions than answers. What was someone doing with both deer antlers and a welding helmet? Why was someone carrying around a piece of parchment with sap on it? How could anyone forget an entire tank full of fish?

Of the 50 items on the list, we’ve selected 25 of the best ones, which you can enjoy in the list below.
