Quirks are new heavy particles that are charged under a new strong 
force and exhibit unusual dynamics when produced at a collider. 
I will briefly explain what quirks are, why they are motivated and 
introduce some of the unusual signals they may lead to at the LHC. 
The quirk scenario provides new interesting challenges for the LHC 
experiments, such as non-circular muon-like tracks and events with 
unusual patterns of soft photons or pions.
