A number of Aviva Premiership rugby players were recently tested on their car knowledge by breakdown provider Green Flag.
The company, which is a sponsor of the league, decided to gather members from Wasps, Harlequins and Bath Rugby and trick them by inventing names of vehicle parts.
Wasps trio Christian Wade, Sailosi Tagicakibau and Nathan Hughes found it simple to answer questions about what car they drive, but they looked baffled when faced with questions about made-up components under the bonnet.
The same applied to Quins players Marland Yarde, Nick Evans and Ugo Monye, as well as Bath stars Matt Banahan, Francois Louw and Matt Garvey.
Watch the players try to take on the trick questions in the video below:
