Looking for new laws of elementary interactions is one of the mandates of the Large Hadron Collider (LHC). One distinguishing criterion, often used in these searches, is large amount of missing transverse momentum, carried away by weakly interacting massive particles. However, this criterion may not be fulfilled in a number of well-motivated theoretical scenarios. I plan to discuss several such situations, their characteristic signatures in the form of multiple leptons, and the criteria for distinguishing among various scenarios of this kind. In this connection, I wish to emphasize the usefulness of one type of signals recently emphasized by us, namely, same-sign trileptons and four-leptons.
