Friday's episode of The Amazing Race is so nuts — or should we say "sew nuts"?

At one of the Detours, teams have to make a traditional Georgian candy, Churchkhela, by threading five strings of hazelnuts. That's a lot more difficult — and bloodier — than it sounds.

Check out the exclusive sneak peek above to see who's having a tough time - and who's driving Tyler (hazel)nuts.

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