Jimmy is eating a burrito (a stuffed, soft wheat flour wrap) while Venus talks to him. When she pauses he points his burrito at her and asks: "do you want a taco?" Tacos are typically hard shell and made of yellow corn, but even the soft shell ones are open ended and look like half a moon, as opposed to a burrito which is more of a padded---and closed---rectangle.
When Ted introduces Venus to Jimmy, he says "She's from Greece". Actually, Aphrodite was from Greece, Venus was her Roman equivalent. The same, her father is Zeus, but Venus' father is Jupiter---the roman equivalent to Greek Zeus. To avoid such confusion, Vanna White's character ought to have been named "Aphrodite" instead, since all the other mythology references (Medusa, etc.) are Greek.
