The most convincing place to find a glueball would be in a channel with exotic quantum numbers ($J^{\mathrm{PC}}=0^{--}$, ${\mathrm{even}}^{+-}$, ${\mathrm{odd}}^{-+}$). We enumerate the allowed and forbidden few-body decay modes of such exotic mesons. In the particular case of the $0^{+-}$, the set of allowed few-body decay modes is itself a unique signature. For other $J^{\mathrm{PC}}$ values the signature depends on some-what more detailed characteristics of the allowed decays, which we enumerate.
