I will discuss stellar evolution in close binaries and highlight some exotic outcomes. Examples of the differences from single stellar evolution will be shown and in particular I will focus on three cases: ultra-stripped Type Ic SNe, progenitor evolution leading to accretion-induced collapse of massive ONeMg white dwarfs, and thermal evolution of low-mass (proto) helium white dwarfs. If time permits, I may say a few words about hypervelocity stars as well.
