  Recently, the ZEUS collaboration has reported on several remarkable
properties of events with a large rapidity gap in deep inelastic scattering. We
suggest that the mechanism underlying these events is the scattering of
electrons off lumps of wee partons inside the proton. Based on an effective
lagrangian approach the $Q^2$-, $x$- and $W$-distributions are evaluated. For
sufficiently small invariant mass of the detected hadronic system, the
mechanism implies leading twist behaviour. The $x$- and $W$-distributions are
determined by the Lipatov exponent which governs the behaviour of parton
densities at small $x$.
