That's exactly what they did, along with Breaking Dawn Part 2 costar Taylor Lautner, during an appearance on the TV show El Hormiguero in Madrid on Thursday.
In addition to chatting up the final installment of the Twilight film franchise, the trio also happily agreed to partake in a little game.
While blindfolded, Pattinson, Stewart and Lautner had to guess when 30 seconds had passed, with Lautner beating out his pals and hitting a buzzer at just the right time, thereby saving an audience member from being doused with a bucket of fake blood.
Meanwhile, Breaking Dawn Part 2 hits theaters today. Fake blood and all.
