I will focus on two topics in top physics - the anomalously large forward backward asymmetry (A_FB) in t-tbar production and the newly suggested signal of dark matter production - single top with missing E_T. Large A_FB may be a sign of new physics, with new flavor symmetric sectors representing an attractive possibility. I will show which representations of SM global flavor group can lead to acceptable phenomenology. As for the second topic, I will show that a monotop signal may be the dominant signal of DM at LHC for a large set of models.
