Research tells us that it’s people like mayors that have hands.

Our reading
An editorial interpretation.
The speaker delivers an absurd claim in the flat manner of a scientific finding, suggesting that hands belong especially to officials like mayors. The humour lies in the deadpan appeal to research, which makes a nonsensical generalisation about who has hands sound authoritative and carefully established.
