Опель: Ну, Філе, ласкаво просимо назад на Землю. Філ: Дякую, пані. Пані Вінфорд... Я маю на увазі Opel.

Opel: Чи були у вас проблеми під час подорожі в космос?

Філ: Серйозних проблем у нас не було, але це був точно не пікнік.

Опель: Ой, справді? Філ: Так. Це було не дуже зручно.

Opel: А як щодо їжі? Це була проблема?

Філ: Ну, у нас не було нормальної їжі. Opel: Що у вас було?

Філ: У нас були харчові таблетки та інші види їжі в тюбиках.
