Our reading
An editorial interpretation.
The speaker brags of having mind control over another man, then undercuts it by describing the routine: he tells them to shut up, they go quiet, and they resume talking once he leaves. The joke is that the supposed power is really obedience, with defiance only when safely out of earshot.
