  We discuss production of two pairs of $c \bar c$ within a simple formalism of
double-parton scattering (DPS). Surprisingly very large cross sections,
comparable to single-parton scattering (SPS) contribution, are predicted for
LHC energies. Both total inclusive cross section as a function of energy and
differential distributions for $\sqrt{s}$ are shown. We discuss a perspective
how to identify the double scattering contribution.
