Nothing beats Rod Hull. Pure anarchy. Emu didn't speak, but didn't need to. Amazing act. The concept of a puppet that loved children but saw adults as fair game for getting their heads kicked in was genius.
Funnily enough he never bothered Billy Connolly - maybe due to Connolly informing him that should the bird attempt to 'do a Parky' on him the bird's f****** neck and Hull's f****** arm would be broken without hesitation
