The honeymoon is definitely over for one of The Amazing Race's blind date couples.

On Friday's episode (8/7c, CBS), Jeff and Jackie chew each other's heads off after getting lost in Bavaria (in lederhosen, natch). Things get worse and way more uncomfortable after they stumble upon another team's car — with their fanny pack still in it — and decide to take off with it.

"Respect me when I'm talking," Jackie says. "Don't cut me off ever again. Ever again. Just don't do it!"

"Do us both a favor and read the clue," Jeff snaps. "God, you're so f---in' annoying!"

Check out their fight above — and see who left their fanny pack behind.

The Amazing Race airs Fridays at 8/7c on CBS.
