One wild night of drinking can make a big impact on your cherished Uber rating.

On Monday's Jimmy Kimmel Live, Kimmel and guest Ashton Kutcher compared their scores — and though they were close, Kimmel's took the prize by a margin of 0.01.

"I know what happened," Kutcher said. "I had a bad night ... with Mila [Kunis]' dad where we were drinking vodka."

Whoops. Still, 4.79 is nothing to sneeze at.
