Uber Technologies Inc. has made a list of the most outrageous items riders have forgotten in Canadian Uber cars. The company says Canadians left behind glass eyes, gold teeth, a black whip and even a graduation certificate in the vehicles they were riding in. The list also included poutine, homework, a ukuleles, wedding cards, dentures and a shower curtain pole. Uber says the riders who lost the most items last year were using the service in Lethbridge, Alta., the Niagara and Kitchener-Waterloo regions of Ontario and Montreal. Uber says users were most forgetful on Saturdays and Sundays and between the hours of 11 p.m. and 1 a.m. Uber says Jan. 1 and Oct. 29, the Friday closest to Halloween, had the most items lost in its vehicles in a day. The company's data shows users were most likely to forget watches on Monday, headphones on Tuesday, laptops on Wednesday, books on Thursday, passports on Friday, phones on Saturday and cakes on Sunday.
