That '70s Show - Season 5 Episode 11 -

When Fez finally agrees to present his DMV girlfriend Nina to the gang, Kitty decides to give a formal dinner party, just when Red wanted to see an annual TV challenge special, Battle of the Network Stars. Eric and Hyde object to their girls making them come; when Jackie even wants Steven to wear decent cloths, he really refuses, so she accepts an invitation from her ex Kelso, who wasn't allowed to come alone. All the men soon run off from the horribly boring party. The boys' last hope to hold out against a girl is Fez- even Kelso knows better.
