We investigate the blow up points of the one--dimensional parabolic Burgers' equation $\partial_t u=\partial_x^2 u-u\partial_xu+u^p$ under a dissipative dynamical boundary condition $\sigma \partial_t u+\partial_\nu u=0$ for one bump initial data. A numerical example of a solution pertaining exactly two bumps stemming from its initial data is presented. Moreover, we discuss the growth order of the $L^\infty$--norm of the solutions when approaching the blow up time.
