  For a long time it has been known that the like-sign dilepton signature can
help establish the existence of a gluino at the LHC. To unambiguously claim
that we see a strongly interacting Majorana fermion -- which we could call a
gluino -- we need to prove that the particle responsible for the like-sign
dilepton events is indeed a fermion. Using only angular correlations in the
same gluino decay cascade which is used to measure its mass, we show how to
distinguish a universal extra dimensional interpretation with a bosonic heavy
gluon from supersymmetry with a fermionic gluino. Assuming a supersymmetric
interpretation, we show how the same angular correlations can be used to study
the left--right nature of the sfermions appearing in the decay chain.
