The next sentence: Once botellas de vino, por favor.
An uncle has hidden eleven bottles in his coat – the eleven comes from football with its eleven players. The uncle is tugging at a boat (once) with two people inside drinking tea and saying “I do”; he gives her a ring shaped like a snake (botellas).
Then he stretches (de), and you see a winemaker singing from sheet music (vino). Back at the lake the gate is waiting again (por favor).
By the way: vino can also sound like bino – both are understood.
