Can you explain the joke to me? I know it's something to do with Pyrros Dimas being appointed in charge of the ballot system of PASOK.
It was something his coach used to shout at him in order to encourage him when he was competing: «Κάτσε κάτω από την μπάρα!» ("Stay under the bar [and lift the barbell]") If you google the Greek phrase, I'm sure you'll find youtube videos with the original scene.
The coach's words have become very famous, mostly because Pyrros Dimas won golden metals in the Olympics. Bernadina is playing with words, because Pyrros Dimas is now a candidate MP with PASOK, whose leader is Evangelos Venizelos, or "Bennie", as he is called jocularly (
or affectionately, depends if you're a voter or not ). Bernadina is basically saying: "Pyrro, stay under Bennie [and lift him to support him]". I'm sure she'll explain herself, though :)
