We study the charmful three-body baryonic B decays with $D^{ (*)}$ or $J/\Psi$ in the final state. We explain the measured rates of $\bar B^0\to n\bar p D^{ *+}$, $\bar B^0\to p\bar p D^{ (*)0}$, and $B^-\to \Lambda \bar p J/\Psi$. In particular, the branching fraction of $\bar B^0\to\Lambda\bar \Lambda D^0$ predicted to be of order $2.3\times 10^{ -6}$ is in accordance with the Belle measurement, $(1.05^{ +0.57}_{ -0.44}\pm 0.14)\times 10^{ -5}<2.6\times 10^{ -5}$.
