If you were traveling with your college diploma, diamond-encrusted gold grills or a letter from your incarcerated boyfriend, chances are you'd hold onto them pretty tight, right?
Apparently not, according to Uber. The ridesharing service has released its annual list of the 50 most unique or outrageous personal possessions left behind in its cars, and this year's list includes some odd ones.
Top 10 things left in Uber vehicles:
Other odd things rounding out the top 50 include tax returns, a marriage certificate, a ukelele, a box of hair extensions, a bulletproof vest, a jetpack, a leaf blower, a college diploma and a bridal veil.
Unsurprisingly, Uber said the most common times for items to be left behind are between 10 p.m. and 2 a.m. on Saturday and Sunday, with additional upticks around happy hour on weekdays.
According to Uber, riders who realize they have left an item behind should contact their driver as soon as possible and provide a detailed description of the lost item. Riders who forget their phone in a car can use Uber's website to report their missing item.
